(FORTUNE) – The Supreme Court has blocked a citizenship question from being added to the 2020 U.S. Census for now, a major blow to President Donald Trump.
In a narrow ruling, the court said in the case the Trump administration did not give reasons to add a citizenship question to next year’s census. The administration argued that the question was necessary to enforce the Voting Rights Act. The decision is seen as a stunning win for civil rights groups and advocates opposing the addition, believing that it would lead to an inaccurate count of the nation’s population.
Critics also say Trump’s camp wanted to reduce the number of people counted as minorities in democratic districts. Data from the 2020 census is used to allocate congressional seats and distributing billions of federal dollars to states and municipalities in the next decade.
