LEGAL PRINCIPLE: CIVIL PROCEDURE – Res Judicata – Issue Estoppel – Nature and Scope
PRINCIPLE STATEMENT
There are two kinds of estoppel by record inter partes or per rem judicatam; the first is usually referred to as 'cause of action estoppel' and it occurs where the cause of action is merged in the judgment; there is, however, a second kind of estoppel inter partes and this usually occurs where an issue has earlier on been adjudicated upon by a court of competent jurisdiction and the same issue comes incidentally in question in any subsequent proceedings between the same parties (or their privies); in these circumstances, 'issue estoppel' arises; this is based on the principle of law that a party is not allowed to (i.e. is precluded from) contending the contrary or opposite of any specific point which having been once distinctly put in issue, has with certainty and solemnity been determined against them.

"There are two kinds of estoppel by record inter partes or per rem judicatam... The first is usually referred to as 'cause of action estoppel' and it occurs where the cause of action is merged in the judgment... There is, however, a second kind of estoppel inter partes and this usually occurs where an issue has earlier on been adjudicated upon by a court of competent jurisdiction and the same issue comes incidentally in question in any subsequent proceedings between the same parties (or their privies); in these circumstances, 'issue estoppel' arises. This is based on the principle of law that a party is not allowed to (i.e. he is precluded from) contending the contrary or opposite of any specific point which having been once distinctly put in issue, has with certainty and solemnity been determined against him."
EXPLANATION / SCOPE
This comprehensively distinguishes two types of res judicata estoppel: Type 1—Cause of action estoppel: Entire cause of action merged in judgment—prevents re-litigating entire claim. Type 2—Issue estoppel: Specific issue adjudicated—prevents re-litigating that issue when it arises incidentally in subsequent proceedings. Issue estoppel characteristics: (1) Issue previously adjudicated by competent court; (2) Same issue arises incidentally in later proceedings; (3) Same parties (or privies); (4) Party precluded from contending contrary of what was determined. “Distinctly put in issue” means: issue was clearly raised, joined, and addressed in prior proceedings. “With certainty and solemnity” means: judicially determined with full consideration and finality. “Determined against him” means: party lost on that issue in prior proceedings. Underlying principle: Party cannot: re-argue point decided against them, contend opposite of prior determination, or avoid binding effect by raising issue in different action. This serves: finality (issues once decided stay decided), consistency (preventing contradictory determinations), and efficiency (avoiding endless re-litigation). Issue estoppel is narrower than cause of action estoppel—doesn’t require identical causes of action, only that specific issue was decided and arises again. This flexibility allows: estoppel on component issues, preventing re-litigation even in different contexts, while focusing on specific determinations not entire claims.
