For issue preclusion, also known as collateral estoppel, to be enforceable against a party, it is essential that the party was a participant in the original case. This requirement ensures that the party had the opportunity to litigate the issue in question. The fundamental idea behind issue preclusion is to prevent re-litigation of an issue that has already been conclusively resolved in a prior action.

If a party was not involved in the first case, they cannot be bound by its outcomes, regardless of the circumstances surrounding the litigation. This principle reflects a basic tenet of fairness in the legal system, which dictates that one should not be held accountable for a decision in a case where they had no opportunity to present their side or to defend their interests.

The other options do not encompass the core necessity for issue preclusion. Winning or losing in the first case, having legal representation, or the role of being a plaintiff are not prerequisites for a party to be subject to issue preclusion. Thus, the importance lies in the participation of the party in the original litigation.
