Oct. 15 (UPI) -- The U.S. Supreme Court on Wednesday is set to revisit a congressional map case it first heard earlier this year that could give Republicans an even greater majority in the U.S. House.

The case, Louisiana vs. Callais, first went before the high court in March, but justices declined to hand down a decision at the time.

They are considering whether a congressional map -- redrawn in 2024 to ensure there were two Black-majority districts -- violates the 15th Amendment and the Equal Protection Clause of the 14th Amendment. The Equal Protection Clause was enacted to protect voting rights for the formerly enslaved and the 15th Amendment prevents the government from denying voting rights based on race.

Louisiana lawmakers redrew the congressional map in 2024 to comply with a court ruling that said the Republican-controlled legislature had illegally disenfranchised Black voters under its previous redistricting plan based on the 2020 census. The ruling said the original map violated the Voting Rights Act.
