(The Center Square) — Maine has agreed to temporarily suspend a new voter-approved law limiting contributions to super PACs in response to a lawsuit challenging the constitutionality of the new requirements.

Question 1, one of four referendums approved by Maine voters in the Nov. 5 elections, sets a new limit of $5,000 for contributions to independent expenditure groups that spend money independently to support or defeat candidates in federal, state and local elections. The bipartisan measure was approved by nearly 74% of Maine voters, according to state election results.
