A legal battle over Missouri's congressional map has returned to the US Supreme Court. The dispute centers on an effort to gain an additional Republican seat in this year's midterm election. A group called People Not Politicians has filed an emergency appeal, seeking to block the proposed map from being used.

The appeal follows a series of rapid developments in the case, involving four different courts over 24 hours. People Not Politicians warns that allowing the map to proceed could cause confusion and disruption for election officials. Further details on the case are available from the source.
