Read the full text of the Supreme Court's decision to block a census citizenship question

WASHINGTON – The Supreme Court on Thursday put a halt – at least temporarily –to the Trump administration's effort to add a citizenship question to the 2020 census, with Chief Justice John Roberts writing that Commerce Secretary Wilbur Ross' justification for the question's inclusion appeared to be "contrived." 

"The evidence tells a story that does not match the explanation" given by Ross, Roberts wrote. He said that the Administrative Procedures Act requires "reasoned decisionmaking" with "an explanation for agency action." 

"What was provided here was more of a distraction," Roberts said. 

The complex decision included several dissents and concurrences, with the court's four liberal justices saying they would have struck down the citizenship question outright, while the court's four other conservative justices said it should have been upheld.
