Pennsylvania’s highest court on Sept. 12 rejected a request from Democratic Gov. Tom Wolf that it immediately take up his challenge to Republican legislation that has bundled a constitutional amendment regarding abortion with four unrelated proposed changes.

In turning down Wolf’s request, the justices said he was free to file a legal action before the lower-level Commonwealth Court. The amendments could go before voters as early as May. Wolf filed the legal action in late July, arguing that bundling together the measures in a bill before the politically divided Legislature violates a constitutional rule against passing laws that address multiple, unrelated topics.
