Groups challenging the state’s new congressional districts are asking for documents and testimony explaining why the Legislature might have destroyed records that could be relevant to the case.

In a series of filings this week, the League of Women Voters of Florida and its allies in the lawsuit demanded records about decisions by the House and the Senate to get rid of documents related to redistricting. The coalition of map opponents argues that the new districts violate the anti-gerrymandering Fair Districts standards approved by voters in 2010.
