From North Carolina to Oklahoma, lawmakers are trying to rein in judges in response to court rulings they don't like. The latest effort is in Pennsylvania, where 12 Republicans last week introduced resolutions to impeach the Democratic justices who threw out a GOP-drawn congressional map.

Why it matters: This growing trend of reshaping or constraining state courts, observers argue, undermines the independence of the states’ judiciary to issue rulings solely based on the law.
