PURSUANT TO NEW YORK CITY CIVIL COURT ACT 1808, COLLATERAL ESTOPPEL OR ISSUE PRECLUSION DOES NOT APPLY TO SMALL CLAIMS ACTIONS, BUT RES JUDICATA OR CLAIM PRECLUSION DOES APPLY TO SMALL CLAIMS ACTIONS (CT APP). ​

The Court of Appeals, in a full-fledged opinion by Judge Stein, over an extensive dissent, interpreting New York Civil Court Act section 1808, determined a judgment in a small claims action is subject to the transactional approach to claim preclusion. Plaintiff won a small claims case seeking overtime wages. Then plaintiff brought another action in federal court seeking additional damages for the failure to pay overtime wages under federal and state law. The Second Circuit asked for clarification of the meaning of section 1808, which could be interpreted to prohibit the application of both issue preclusion and claim preclusion to small claims actions. Under the statute, collateral estoppel or issue preclusion does not apply to small claims actions, but res judicata or claim preclusion does:

We now conclude that, under NY City Civ Ct Act § 1808, small claims judgments do not have collateral estoppel or issue preclusive effect (with one exception), but such judgments may have the traditional res judicata or claim preclusive effect in a subsequent action involving a claim between the same adversaries arising out of the same transaction or series of transactions at issue in a prior small claims court action. * * *

… [T]he claim preclusion rule extends beyond attempts to relitigate identical claims. We have consistently applied a “transactional analysis approach” in determining whether an earlier judgment has claim preclusive effect, such that “once a claim is brought to a final conclusion, all other claims arising out of the same transaction or series of transactions are barred, even if based upon different theories or if seeking a different remedy” … . * * *

Collateral estoppel, or issue preclusion, is related to, but distinct from, the doctrine of res judicata. Collateral estoppel prevents “‘a party from relitigating in a subsequent action or proceeding an issue clearly raised in a prior action or proceeding and decided against that party . . . whether or not the . . . causes of action are the same'” … . Simmons v Trans Express Inc., 2021 NY Slip Op 03484, CtApp 6-3-21
