Commission Comment: PL 2-15, which took effect April 6, 1981, applies to “any cause of action within the provisions of [7 CMC §§ 1102 and 1103] upon which the process issues arose which (had) not been reduced to judgment” as of that date. PL 2-15, § 5. Section 4 of PL 6-25, the “Commonwealth Judicial Reorganization Act of 1989,” provides that “[w]herever the term ‘Commonwealth Trial Court’ appears in the Commonwealth Code, it is henceforth to be interpreted and understood to refer to the Commonwealth Superior Court.” PL 6-25 also established the Commonwealth Supreme Court as the Commonwealth’s appeals court; see 1 CMC § 3101 et seq.
