A unanimous decision has been made to block new congressional districts from being used. These districts were backed by a prominent political figure and had been hoped to help one party win an additional seat. An appeal to a higher court is planned, with the state's attorney general claiming a constitutional crisis has been triggered.

The blocked districts were set to be used in an upcoming election, but will now be subject to a statewide vote. This vote will determine whether the new map is upheld or rejected.

Further information on this development is available from the source, including the potential implications of the decision and the appeal process.
