preclusion

Definition

The legal equivalent of slamming a door in someone's face—it's when you're prevented from doing something, raising an issue, or re-litigating a matter that's already been decided. Courts use preclusion doctrines to prevent parties from getting infinite do-overs on the same legal questions. Once the gavel falls and preclusion kicks in, that argument is dead and buried, no matter how much you'd like to resurrect it.

Example Usage

The doctrine of issue preclusion prevented the plaintiff from challenging the patent's validity again, since that battle had already been lost in federal court.

constructive

In legal contexts, something that doesn't actually exist but the law pretends it does for fairness reasons—like constructive notice or constructive eviction. It's the legal system's version of "let's agree to pretend this happened so we can achieve justice." Outside law, it just means feedback that's actually helpful rather than disguised criticism, though good luck finding much of that.
