TAT review, judicial review and civil remedies after an occupational injury

Overview

A final occupational injury decision does not open a new appeal simply because a party disagrees with the result. After the Tribunal administratif du travail (TAT) has decided, internal review or revocation (révision ou révocation) serves limited statutory grounds. Judicial review (contrôle judiciaire) serves the Superior Court's supervisory function. A civil action against a person responsible for an injury asks a different question and encounters the compensation scheme's statutory immunities.

The remedy follows the alleged wrong. A genuinely undiscoverable fact, an inability to be heard, an invalidating defect, an unreasonable administrative decision and a third person's civil fault require different allegations and evidence. This lesson uses the Act to establish the Administrative Labour Tribunal (AITAT), especially ss. 49–51, and the Act respecting industrial accidents and occupational diseases (AIAOD), especially ss. 438–447, to distinguish these routes. No route automatically preserves the time limit for another.

Learning Objectives

• Apply the grounds, timing and procedural requirements for internal TAT review or revocation.
• Distinguish judicial review of the merits from procedural fairness review and an ordinary appeal.
• Identify civil immunity, permitted third-party proceedings, election requirements and subrogation consequences.

Choose the remedy by identifying its object

Administrative review by the CNESST occurs before the usual contestation before the TAT. Reconsideration by the CNESST has its own grounds. Neither describes an application asking the TAT to reopen its final decision. The latter belongs to ss. 49–50 AITAT and is exceptional. Starting a new CNESST claim or sending further medical material to an agent does not itself attack the TAT's conclusions.

Identify the operative disposition (dispositif): what did the Tribunal grant, refuse or declare? Internal review ordinarily challenges an adverse conclusion, not merely a sentence in the reasons with which an otherwise successful party disagrees. An observation unnecessary to the outcome does not generally justify reopening the decision. The requested correction must have a practical effect on rights or obligations decided.

Section 51 AITAT makes the Tribunal's decision final, without appeal, and enforceable according to its terms. Filing it in the Superior Court registry for enforcement does not create an appeal or eliminate the Tribunal's statutory review power. Likewise, the finality and privative provisions do not abolish the Superior Court's constitutionally protected supervision. Finality and supervision perform different functions within the same system.

Review can correct a decision when a statutory ground permits intervention; revocation can annul it and restore the matter for determination, often through another hearing. The appropriate order depends on the defect and what remains to be decided. An application should therefore specify both the conclusion attacked and the remedial consequence sought, rather than simply demand that the file be reopened.

Establish a statutory ground for internal review

New facts and an inability to be heard

Section 49 AITAT identifies three grounds. The first concerns a new fact which, had it been known in time, could have justified a different decision. A new fact (fait nouveau) is not simply information placed in the record for the first time. It ordinarily must concern a fact existing at the original hearing, discovered later and unavailable despite the applicant's diligence. The applicant must explain its significance for the outcome.

A later diagnostic examination may reveal a condition already present at the hearing. By contrast, a new expert's disagreement with an earlier opinion, a later scientific publication or an argument deliberately held in reserve does not automatically satisfy this ground. The question is whether the newly discovered fact meets the statutory requirements, not whether a second presentation of the case would be stronger. The jurisprudence varies in how strongly it describes the fact's potential effect; a careful application demonstrates why it could materially change the decision.

The second ground concerns a party who could not present observations or be heard for reasons considered sufficient. Serious, credible circumstances matter. The standard does not necessarily demand absolute impossibility, but it does require an explanation connecting the circumstances to the lost opportunity. A notification failure or an administrative mistake may be relevant. Choosing not to attend, ignoring communications or regretting a litigation strategy will not ordinarily supply sufficient reasons.

The applicant must establish the ground relied on. Assertions in a letter do not replace evidence of when a fact was discovered, what efforts preceded discovery, or why participation was prevented. Correspondence, medical material or evidence about a failed notification should address those issues directly. Proof that would help the original merits dispute is not necessarily proof that the decision may lawfully be reopened.

An invalidating substantive or procedural defect

The third ground is a substantive or procedural defect (vice de fond ou de procédure) of a nature likely to invalidate the decision. In Commission de la santé et de la sécurité du travail c. Fontaine, 2005 QCCA 775, the Court of Appeal explains the restrictive character of this mechanism. A serious, obvious and determinative error may justify intervention. A second adjudicator's preference for another interpretation or assessment does not suffice.

Internal review is consequently not a second hearing of every disputed factual inference. A party cannot simply ask another member to believe its witness, adopt its expert's opinion or favour a competing line of decisions. A decisive factual premise unsupported by the record or failure to decide an essential issue can raise a different problem, but the application must demonstrate the defect and its effect. Listing disagreements without making that connection confuses correction of invalidity with an appeal on the merits.

Procedural defects include sufficiently serious breaches of the right to be heard. The context matters: the opportunity actually offered, the party's response, any timely objection and the effect on a fair determination. A party aware of a procedural problem should raise it when it can still be corrected. Remaining silent for tactical reasons and invoking the same problem only after losing may undermine the application.

The Tribunal's reasons need not discuss every document or argument. Concise reasons can still explain the decision intelligibly. An omission concerning a central issue may matter; disagreement with emphasis or the absence of an exhaustive discussion ordinarily does not. Do not import the whole judicial reasonableness framework into s. 49(3): the statutory question remains whether an invalidating defect is established.

Worked example: a later scan and an existing disagreement

Factual Scenario

An application alleging a recurrence is dismissed after the hearing. A subsequent scan reveals a structural condition that, according to the medical evidence, already existed at the hearing but could not reasonably have been detected earlier. The worker seeks internal review and provides the scan, the medical explanation, the earlier investigation history and the date of discovery.

File promptly and prove the procedural conditions

Section 50 AITAT requires an application within a reasonable time (délai raisonnable). It does not prescribe the ordinary time limit for contesting a CNESST decision. Côté et Location Lou-X, 2016 QCTAT 3778 adopts a thirty-day benchmark drawn from judicial review jurisprudence. This is a benchmark within a contextual reasonable-time assessment, not a separate statutory thirty-day appeal period and not an invitation to delay.

Record both the decision date and notification date. The predominant approach starts from notification; a new-fact application also requires attention to discovery. Special circumstances can affect whether the period taken is reasonable. Waiting for a transcript, misunderstanding the law or pursuing an inappropriate route does not automatically excuse inactivity. If lateness is disputed, give a precise chronology and evidence explaining each material interval.

Section 15 AITAT may also be relevant to relief from a failure to act within a prescribed time: reasonable grounds and absence of serious prejudice to another party must be demonstrated. Distinguish that relief analysis from the initial assessment under s. 50. A party cannot assume that the opponent's inability to identify prejudice alone supplies the missing explanation for delay.

The written application must state its grounds. A timely allegation followed by clarification differs from adding a wholly new ground after an unjustified delay. The Tribunal may decide on the record unless a party requests a hearing or the Tribunal considers one necessary. Where the alleged ground is an invalidating defect under s. 49(3), the member who rendered the original decision cannot decide that application. The same exclusion does not automatically govern the first two grounds.

An interlocutory decision (décision interlocutoire) may raise review questions before the merits decision, but ordinary disagreement with case management does not justify interrupting proceedings. Serious consequences that cannot be corrected adequately later require particular attention. Continue to respect hearing directions while pursuing the appropriate procedural request; filing an application is not itself permission to disregard the process.

Understand the Superior Court's supervisory role

Reasonableness and procedural fairness

Under Canada (Ministre de la Citoyenneté et de l’Immigration) c. Vavilov, 2019 CSC 65, reasonableness (décision raisonnable) is presumptively the standard for judicial review of administrative merits. The court assesses the justification actually given, read in its legal and factual context. It does not rehear the claim, select its preferred medical opinion or substitute the decision it would have made initially.

A reasonable decision must rest on coherent reasoning and remain justified in relation to the constraints bearing on it. Those constraints include the statutory scheme, the evidence, the parties' central submissions, relevant legal principles and the consequences for the affected person. The applicant must show a sufficiently central flaw. Minor imperfections, isolated wording and an alternative plausible conclusion do not necessarily make the decision unreasonable.

The court begins with the reasons, understood with the record. It should neither hunt for trivial defects nor invent an entirely different rationale to rescue a deficient decision. Expertise and institutional context help explain the reasons; they do not authorize unexplained disregard of decisive evidence or binding legal constraints. Unexplained departures from an established practice may matter, but the existence of divergent administrative decisions does not automatically require correctness review.

Correctness applies to recognized exceptions, including constitutional questions, general questions of law of central importance to the legal system as a whole and certain jurisdictional boundaries between administrative bodies. Calling an issue “jurisdictional” is insufficient. Ordinary interpretation of the TAT's own statute generally remains within presumptive reasonableness. The exceptional category should be identified and justified, not inferred from how strongly a party disagrees.

Procedural fairness (équité procédurale) raises a distinct inquiry: did the procedure provide the fairness required in the circumstances? The court does not defer to an actual denial of the right to be heard. Nevertheless, an evidentiary or case-management ruling is not automatically a fairness breach. Distinguish a complaint about the weight given to admitted evidence from exclusion of material evidence in circumstances that deprived a party of a fair opportunity to present its case.

Alternative remedies, timing and the resulting order

Judicial review is discretionary. An adequate alternative remedy and prematurity may justify declining intervention. Internal review is not invariably a compulsory preliminary step: Wal-Mart du Canada c. Commission des relations du travail, 2006 QCCA 422 explains why a limited internal correction mechanism is not equivalent to a true appeal. The court assesses the available alternative in context. Conversely, going directly to court does not guarantee that it will exercise its discretion.

Premature review of interlocutory rulings generally disrupts the administrative process. Exceptional circumstances, such as a manifest absence of power or a serious violation with consequences that cannot adequately be repaired later, require a focused explanation. The cost and inconvenience inherent in continuing a hearing ordinarily do not alone establish the exception. Judicial review must also be pursued promptly within the applicable reasonable-time requirements; it is not an indefinitely available substitute for missed remedies.

Where judicial intervention is justified, the usual course is to set aside the decision and return the matter to the administrative decision maker. The court may exceptionally resolve the matter where the result is inevitable or the circumstances justify avoiding another futile round. Delay, fairness and practical consequences bear on the remedy. A successful application therefore does not necessarily mean an immediate award of compensation.

Worked example: refusal to reopen does not create an appeal

Factual Scenario

The TAT rejects an employer's preferred interpretation after discussing the statutory text and contradictory evidence. Another member refuses internal review because the employer has shown disagreement but no invalidating defect. The employer then seeks judicial review of both decisions.

Separate civil liability from compensation proceedings

Identify the defendant and the injury being claimed

Civil immunity (immunité civile) under s. 438 AIAOD bars the worker's civil action against the employer because of the occupational injury. Section 439 addresses the beneficiary's action following a worker's death. The scheme exchanges ordinary fault litigation for statutory compensation. Béliveau St-Jacques c. Fédération des employées et employés de services publics inc., [1996] 2 R.C.S. 345 explains this structure and its application to damages sought under the Quebec Charter.

The bar is not limited to amounts actually paid by the CNESST. Costco Wholesale Canada Ltd. c. Roadnight, 2021 QCCA 17 emphasizes that a worker cannot make the compensation scheme optional by declining its remedies and then seeking equivalent redress through civil liability. An uncompensated head of loss does not by itself defeat immunity. Nor does describing the employer's conduct as intentional automatically remove an occupational injury from the scheme.

Under s. 442 AIAOD, a worker or mandatary of a covered employer is protected for fault committed in the performance of duties, subject to the statutory health-professional exception relating to s. 31 injuries. Identify the person's actual role and the connection between the fault and those duties. G.G. c. S.M., 2019 QCCA 853 rejects simply replacing “in the performance” with the broader idea of an event occurring on the occasion of work. Coverage of the victim and immunity of the alleged wrongdoer are separate questions.

The essential nature of the claim also matters. Compensation for an injury's psychological consequences differs from damages for injury to reputation itself. A non-compensatory order or an independent wrong committed through abusive proceedings can require a separate analysis. Merely renaming injury-related damages does not create jurisdiction. Statutory harassment remedies require a distinct analysis: section 123.16 of the Act respecting labour standards coordinates the remedies in paragraphs 2, 4 and 6 of section 123.15 with occupational-injury compensation for the relevant period. Punitive damages now have their own paragraph, 4.1, outside that restriction. They remain available in the statutory harassment proceeding when the applicable conditions are established; the preceding civil-immunity analysis does not bar every punitive remedy.

Permitted third-party proceedings and proof

Section 441 AIAOD permits proceedings against a covered employer other than the injured worker's own employer only in specified circumstances: Criminal Code fault, recovery of excess loss, responsibility for an injury covered by s. 31, or an employer personally liable for benefits. A stranger who has no applicable statutory immunity must be assessed under the relevant civil rules. Identify legal status before assuming that every business at a worksite enjoys the same protection.

The excess loss (excédent de la perte) route is not another no-fault compensation claim. Under art. 1457 of the Civil Code of Québec, the claimant must establish fault, injury and causation. Civil damages are assessed under the applicable civil rules, including art. 1611, with credit for corresponding statutory benefits. Avoid double recovery, compare the appropriate heads of loss and address any contributory fault. The difference between a salary and a benefit is evidence of possible loss, not automatic proof of the defendant's liability.

The Criminal Code branch requires the relevant guilty plea or final conviction and is subject to the special six-month action period in s. 441. A provincial regulatory offence is not enough to satisfy that branch merely because it concerns workplace safety. Other rules may independently prevent an action: for bodily injury caused by an automobile, ss. 83.57 and 83.63 of the Automobile Insurance Act coordinate compensation and preclude ordinary civil recovery within their scope.

Worked example: benefits and a supplier's fault

Factual Scenario

A worker receives compensation after a supplier's defective installation causes an occupational injury. Assume the supplier is a covered third-party employer and no automobile regime applies. The worker seeks a further amount for proven losses exceeding the corresponding benefits.

Coordinate election, subrogation and limitation periods

An election of remedies (option de recours) under s. 443 AIAOD is required where a civil action is available. The ordinary notice period is six months, with the statutory starting event depending on accident, medically established and communicated occupational disease, or resulting death. For death, the doctrinal source identifies the starting point as the date when it is medically established that the death resulted from the employment injury; the death date alone should not be used mechanically if that link is established later (Fascicule 20, no. 39). The applicable worker's claim for an injury resulting from sexual violence has a two-year election period. The criminal-fault branch has its own starting event tied to the guilty plea or final conviction. Distinguish this election period from the six-month civil-action period in s. 441.

If the beneficiary chooses civil proceedings and recovers less than the statutory benefit, s. 444 permits claiming the difference from the CNESST within six months of the final judgment. If the beneficiary chooses statutory benefits, s. 445 preserves the permitted claim for excess loss. These rules do not authorize a civil claim against an otherwise immune defendant. They operate only once the availability of the civil route has been established.

Subrogation (subrogation) under s. 446 transfers to the CNESST the beneficiary's rights against the responsible person to the extent of benefits paid and the capital value of future benefits. A settlement that deprives the CNESST of that recourse is not opposable to it without ratification. Section 447 addresses interruption of prescription in its favour by the beneficiary's action. A worker's settlement authority over a personal claim does not include authority to dispose freely of the CNESST's claim.

Civil prescription (prescription) must be analyzed separately, including arts. 2925–2926 and 2930 of the Civil Code of Québec, the nature and manifestation of the injury, and applicable special rules. A CNESST claim does not itself interrupt the civil limitation period. Nor does a civil action automatically replace a compensation claim or required election. Federal Crown employees have a distinct election and subrogation framework under the Government Employees Compensation Act; the Quebec rules should not be transferred to them mechanically.

Practice Checklist

• Identify the decision, its operative conclusions, notification date and exact remedy sought.
• For internal review, prove a statutory ground and explain diligence, materiality, timing and any requested relief from lateness.
• For judicial review, distinguish merits from fairness, identify the applicable standard and address adequate alternative remedies and prematurity.
• For civil proceedings, classify each party, the actual injury claimed and the applicable immunity or exception before calculating damages.
• Maintain separate dates for election, civil prescription and administrative remedies; identify corresponding benefits and preserve the CNESST's subrogated rights in any settlement.
