Court Allows Lawsuit to Block Toxic Plants in Louisiana's 'Cancer Alley'

Lawsuit alleges Black residents have been intentionally subjected to harmful pollution for decades.

Published on Feb. 21, 2026

A federal court has ruled that a lawsuit can proceed against the construction of industrial plants in two majority-Black districts of St. James Parish, Louisiana. The lawsuit alleges that these plants, which have disproportionately been built in Black communities in the region known as 'Cancer Alley', violate the 13th and 14th Amendments of the U.S. Constitution.

Why it matters

The lawsuit represents a landmark case in the fight against environmental racism, as Black residents in Louisiana's 'Cancer Alley' have long faced higher rates of cancer and other health issues due to the concentration of polluting industrial facilities in their communities. The outcome of this case could have significant implications for how environmental justice is addressed across the country.

The details

The lawsuit alleges that since 1958, at least 28 of the 32 industrial plants built in St. James Parish have been located in the two majority-Black districts, while no plants have been built in majority-white sections of the parish in nearly 50 years. The region between New Orleans and Baton Rouge, known as 'Cancer Alley', is home to about 25% of the United States' petrochemical processing plants and has seen elevated rates of cancer and respiratory illnesses as a result.

  • In 2023, three religious groups representing the area's Black residents filed the lawsuit.
  • On February 9, 2026, a federal judge in New Orleans ruled that the lawsuit can move forward.
