Prohibits legislative bills from embracing more than 1 subject

S 3373 requires all legislative bills (except budget bills) to cover only one topic, clearly stated in the bill's title. This rule prevents "omnibus" bills that bundle unrelated issues into a single measure. The law takes effect March 31, 2025, and applies to all bills introduced after that date. It directly affects lawmakers drafting bills and the legislative process, not specific constituents or policies.
