It first has to go through the lower courts..
So specify which challenge?
Be specific and not a fantasy world of unicorns and rainbows
One challenge might be over corporate entitlement to personhood with respect to civil rights.
It was decided a hundred years ago that corporations do not enjoy Fifth Amendment protection against self-incrimination. Most recently, in 1988 the court ruled that the Fifth protects only the "right of a natural person, protecting the realm of human thought and expression." Only natural persons enjoy protection under the Fifth Amendment.
However, in CU, the court ruled that corporations enjoy the First Amendment right to express themselves the same as natural persons when it comes to making political contributions. The conservative court never did justify how they could be natural persons under the First Amendment after already having decided that they could not be natural persons under the Fifth Amendment.
Chew on that.
