She dissented in a minority opinion against a decision Alito made last week.

Alito made up complete fantasy and misinterpreted his own self to rule against the EPA and rrverse the 9th circuit. It is completely devoid of legal basis outside dictionary definitions and it even references its own arguments incorrectly. Alito literally contradicts himself in his own aegument and just plods right through. Barret calls this out as a failure on the basis of 'ordinary english'.

But it doesn't matter because Alito was in the majority. No matter how meaningless his arguments were or how utterly correct the dissenting opinion is: it is so ordered.
