Advocacy groups came out on top after the Supreme Court declined to review their preliminary victory in their fight against allegedly racist industrial zoning practices in Louisiana.

Without explanation, the justices on Monday indicated that they would not revisit an appellate court’s finding that Inclusive Louisiana and two other groups have legal standing to pursue their challenge against St. James Parish, part of a stretch of the Mississippi River often called “Cancer Alley” because of the many petrochemical plants located in the area.

The advocacy groups must still present their claims to a federal district court in Louisiana, but the Supreme Court’s order — for now, at least — removes a threshold issue that could have tanked their lawsuit before it began.
