Why it matters: Rep. Nicole Collier's court filing is an escalation of a two-week standoff between Texas Democrats and Republicans over rare mid-decade redistricting, which could create up to five additional U.S. House districts favorable to Republicans.

The standoff began on Monday, when Democratic members returned to the Capitol after being out of the state for more than two weeks due to a controversial redistricting map. Rep. Collier refused to agree to leave the chamber under the surveillance of the Department of Public Safety.
