U.S. Constitution - Article 3 Section 2
In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make.
You guys may be right about that but maybe Brewer thinks it’s more pragmatic and less inflammatory to go thru the appeals process to get to the Supreme Court. If so, I think she has a point. The open-borders crowd would have field day if she refused to comply right now.
