They did exactly that in the Garcia case, which was a "big-ticket SCOTUS case". It became politically untenable and they eventually backed down, but the post-ruling response was initially "nuh uh!"

They didn’t ignore it, at most they bullshitted for a while about how they couldn’t bring Garcia back because he was in the hands of the El Salvador and then ultimately did bring him back.
