When a legislature changes procedural rules in a way that closes off a substantive remedy for one class of litigants, constitutional challenges are almost inevitable. The AVOID Act, which rewrites CPLR § 1007 to impose hard deadlines on third-party practice in New York, has features that defendants' counsel will scrutinize carefully. Whether those challenges succeed depends on how courts balance legislative deference to procedural reforms against the constitutional floor that protects litigants' access to courts.
This article examines the constitutional theories most likely to be raised, the doctrinal framework New York courts apply when evaluating procedural statutes, and the arguments on both sides.
The baseline: procedural statutes get substantial deference
Before analyzing specific challenges, it is important to understand the doctrinal starting point. Courts have consistently held that legislatures have broad authority to regulate procedural rules, including statutes of limitations, filing deadlines, and the conditions under which parties may assert claims. This authority is not unlimited, but the threshold for invalidating a procedural rule on constitutional grounds is high.
New York courts evaluating challenges to procedural statutes typically ask whether the legislature had a rational basis for the rule, whether the rule provides a reasonable opportunity to comply, and whether any vested rights are being extinguished rather than regulated. The AVOID Act's supporters will argue that all three conditions are satisfied: the legislative findings document a rational basis rooted in documented delay tactics; the 90-day as-of-right window (for first contractual third-party actions under the chapter amendments) provides meaningful time to act; and no defendant had a vested right to file a third-party complaint at any arbitrary point before trial.
That said, the constitutional analysis depends heavily on the specific provision being challenged and the facts of the individual case.
Due process: notice and opportunity to be heard
The most commonly raised constitutional challenge to deadline statutes is procedural due process. The argument typically runs as follows: the legislature cannot extinguish a litigant's ability to assert a legally cognizable claim without adequate notice and a meaningful opportunity to do so before the door closes.
Defendants may argue that the AVOID Act's 60-day deadline for non-contractual claims, measured from the uncertain "becoming aware" trigger, fails to provide adequate notice of when the clock starts running. If a defendant does not know when "becoming aware" occurred, a statute that begins running from that undetermined date arguably deprives the defendant of a meaningful window to act.
Courts are likely to apply rational basis review to this challenge rather than strict scrutiny, because the right to implead a third party is not a fundamental right. Under rational basis, a court will uphold the statute if there is any conceivable legitimate governmental purpose for the rule, even if that purpose is not perfectly achieved. The legislature's stated goal of reducing delay in personal injury litigation is a legitimate governmental interest, and the deadline structure is rationally related to that goal.
A stronger version of the due process argument concerns cases that were pending when the AVOID Act took effect. Retroactivity challenges ask whether a legislature can impose new deadlines on defendants who had already answered and were proceeding under the prior version of CPLR § 1007. Courts evaluating retroactive application look at whether the party had reasonable reliance on the prior law and whether the new obligation is disproportionately burdensome. Defendants in pending cases who had not yet filed third-party complaints and who reasonably believed they had additional time may have the strongest due process arguments.
Separation of powers: legislative encroachment on judicial rulemaking
New York has a constitutional separation between the courts' inherent authority to govern their own procedures and the legislature's power to enact statutes affecting those procedures. Article VI of the New York Constitution vests in the Court of Appeals the authority to adopt rules for the courts. The question is whether the AVOID Act crosses a line from permissible procedural legislation into an area reserved for judicial rulemaking.
This argument is unlikely to succeed as a categorical matter. New York courts have long upheld legislative enactments that set procedural rules for civil practice, including statutes of limitations and pleading requirements. CPLR itself is a legislative product, and the AVOID Act is an amendment to that code. Courts will almost certainly treat it as a valid exercise of legislative authority over civil procedure.
A narrower separation-of-powers argument targets specific provisions, particularly the hard cap and the court-order requirement for extensions beyond 30 days. Defendants may argue that requiring a judicial finding of good cause before granting an extension is a legislative attempt to define how courts exercise their discretion, rather than merely setting a deadline. This argument has some theoretical traction but faces substantial headwinds: courts routinely operate within legislatively defined standards for granting or denying extensions, and a "good cause" standard gives courts meaningful flexibility.
The right to apportion liability
New York's CPLR Article 14 and 14-A reflect a policy judgment that defendants have a right to seek apportionment of their liability through contribution and indemnification claims. Defendants may argue that the AVOID Act effectively forecloses that right when the deadline passes, because the note-of-issue bar and the 12-month hard cap leave no procedural path to impleader regardless of how meritorious the underlying claim may be.
The counter-argument is that the right to seek contribution does not include a right to assert it at any time through any procedural vehicle. A defendant who misses the AVOID Act deadline retains the ability to pursue contribution through a separate action after the underlying case resolves. Whether that alternative path is practically available and economically rational is a different question, but courts evaluating constitutional challenges focus on whether the right is extinguished entirely, not merely made more difficult to exercise.

Equal protection: is the classification rational?
The AVOID Act applies to all defendants, but its practical burden falls most heavily on construction defendants, insurers, and property owners in multi-party tort litigation. A defendant might argue that this disparate impact constitutes an equal protection violation.
Equal protection challenges to economic and procedural legislation in New York are subject to rational basis review. Under this deferential standard, a law survives unless the classification is wholly arbitrary. The AVOID Act does not classify defendants by protected characteristic; it applies uniform procedural rules to all defendants in third-party practice. The fact that some industries feel its effects more acutely does not create an equal protection violation under rational basis review.
What practitioners should expect
The first AVOID Act constitutional challenges will likely arise in two contexts: motions to dismiss third-party complaints filed after the deadline has passed, where defendants raise the statute's constitutionality as an affirmative defense; and transitional cases where defendants argue that the statute should not apply to pending matters because their answer predated the effective date.
Courts will almost certainly apply rational basis review to most challenges. The statute will survive that review as applied to the prospective deadline framework. Retroactivity arguments for pending cases present a closer question, particularly where the transition period provided defendants limited time to file.
Defendants' counsel should treat constitutional challenges as a secondary strategy rather than a primary defense. The more productive focus is on ensuring that the impleader decision is made before the deadline passes, which forecloses the constitutional question entirely. For a framework on building that operational readiness, the compliance checklist provides a structured approach to identifying and acting on impleader rights before deadlines expire.
The AVOID Act's constitutional durability is ultimately likely to depend less on abstract doctrine and more on how lower courts handle transitional cases and the "becoming aware" trigger. Those early interpretive decisions will shape the statute's practical scope as much as any challenge to its facial validity.
