This is a big deal. This is a major case brought by Ed Blum (who has brought us Shelby County, the Fisher affirmative action case, and others) and litigated by William Consovoy, who also represents President Trump. I was surprised that the arguments did not get greater analysis.
There will no doubt be further appeals, but this non-pub makes it less likely the Supreme Court would get involved. (It still could happen.)
