Claims based on new conduct
Amron v. 3M
In brief

- Alan Amron asked the Supreme Court to review whether claim preclusion (a rule that can bar claims that could have been raised in an earlier case) prevents a claim based on 3M’s alleged new interpretation of a contract after earlier litigation ended.
- Who it affects
- The denial leaves unanswered by the Supreme Court whether Amron’s claim based on 3M’s alleged post-lawsuit contract reading is barred.

What it's about
The Court refused to hear the case (denied review), so it did not decide that issue; Justice Alito took no part.
Amron’s question concerned whether a claim based on conduct that occurred only after an earlier lawsuit ended could be brought in a later case.
Question presented
Whether claim preclusion bars a claim based on an opposing party’s post-litigation conduct — specifically, a materially different interpretation of a contractual obligation first asserted after prior litigation has concluded — where that conduct could not have been raised in the earlier action.
