I thought another article said they ruled against it, because they did not give adequate justification.
U.S. Supreme Court blocks Trump’s census citizenship question, for now
The U.S. Supreme Court handed President Donald Trump a significant defeat on Thursday, ruling that his administration did not give an adequate explanation for its plan to include a contentious citizenship question on the 2020 census and preventing its addition to the decennial survey for now.
Notice how all of the outlets are now adding the “for now” to their initial reporting.
That “for now” is temporary.
The agency simply gives a clearer explanation, and the forms are printed in October rather than July.
