That is kind of interesting, everything I have read indicated there were warrants issued through the FISA court, and numerous rulings that what they were doing was constitutional, all published. Could you point me to an article stating that there was ANY unwarranted surveillance?
So you would accept it as Constitutional if the courts rule that police randomly entering & searching your home without a warrant or probable cause to believe a crime is or is about to be committed is not a violation of the 4th Amendment?
No US court has the power to overrule the US Constitution, secret or otherwise. Any such rulings are by definition unlawful and un-Constitutional. An un-Constitutional law is no law at all, and it is the duty of every US citizen to ignore and/or disobey/violate it if/when it conflicts with the rights and freedoms enshrined in the Constitution.
