What is the doctrine of claim preclusion (res judicata)
Prohibits relitigating the same claim once a final judgment on the merits has been issued (i.e. claim is precluded).
Claim preclusion is typically asserted as an affirmative defense (e.g. Todd can’t sue me for this, he had the opportunity to do so in a prior suit but didn’t”)
Policy reason: encourages efficiency and consistency.
When does claim preclusion exist?
If these 3 elements are met, the claim will be precluded.
What are examples of valid final judgments on merits?
What are examples of decisions that are not considered an adjudication on the merits?

In the pleading stage, when must claim preclusion be raised as a defense?
Since claim preclusion is an affirmative defense, it must be raised in D’s answer or else it is considered waived.
What factors determine whether claims are sufficiently related for the purposes of claim preclusion?
Does claim preclusion bar a party from bringing the claim again if the claim was involuntarily dismissed?
Yes, because unless otherwise specified, involuntary dismissals are “on the merits.”
⚠️ Note: Party can however, refile claim in state court, just not federal court.
Does claim preclusion apply to adverse parties or co-parties?
Adverse parties only.
Issue preclusion, however, applies to both adverse parties and co-parties.
If D fails to assert a compulsory counterclaim, will she later be precluded from filing that same claim?
Yes, except if:

What is issue preclusion (“collateral estoppel”)?
Prohibits relitigation of issues of fact or law that have been previously adjudicated.
⚠️ Note: Much narrower than claim preclusion (which bars whole claim, not just the issue).
Policy goal: prevent inconsistent judgments on the same issue.
What are the elements of issue preclusion?
Does issue preclusion apply if two issues were the reason for the determination?
No, neither issue will be precluded.
What is the difference between mutual collateral estoppel and nonmutual collateral estopel?
Mutual: Being asserted by a party in the prior action.
Nonmutual: Asserted by someone who was not a party to the prior litigation.
Non-mutual issue preclusion typically arises in what scenarios?
Either:
What is nonmutual defensive collateral estoppel and when is it allowed?
When a new D requests that a final judgment against P from a prior suit be enforced (e.g. Dan tries to use Patty’s negligence finding from a prior lawsuit)
Only allowed if P had a full chance to litigate the issue previously.
What is non-mutual offensive collateral estoppel?
P tries to assert a final judgment issued against D from a prior suit.
⚠️ Note: Rarely granted.
What factors do courts balance when deciding whether to allow nonmutual offensive collateral estoppel?
