Unclear? It's about as clear as any prediction we can make about what the Supreme Court will do.

I'm reading "Ketanji Brown Jackson’s Harvard ties raise recusal questions in Supreme Court’s affirmative action case" (WaPo):

In the case before the Supreme Court, it is unclear whether Jackson’s participation would be a deciding factor in the outcome. The slim majority that in 2016 upheld the limited use of race in school admissions has been replaced by a more conservative bloc of six, including three nominees of President Donald Trump. The Trump administration supported those challenging Harvard’s policies as unconstitutional. The Biden administration urged the court not to accept the case.
