How to use invalid in a sentence?

1. Thomas Sowell:

   To include freedom in the very definition of democracy is to define a process not by its actual characteristics as a process but by its hoped for results. This is not only intellectually invalid, it is, in practical terms, blinding oneself in advance to some of the unwanted consequences of the process

2. Tanguy Van Overstraeten:

   If the judges come to the situation where Safe Harbour is not valid then it could be reopening the whole story and that, for many thousands of U.S. companies, would be very difficult because that could mean that in fact the basis of the transfer of data by them would be invalid.

3. Robert Leider:

   If the warrant turns out to be invalid, evidence may still be admitted as long as law enforcement reasonably relied on the warrant when conducting the search, courts will only throw out evidence if the underlying affidavit unquestionably failed to establish probable cause, the warrant failed to specify the place to be searched or the things to be seized, law enforcement lied to get the warrant, or the presiding judge abandoned his judicial role.

4. The Norwegian Supreme Court:

   There was no ground to make the change in regulation invalid.

5. Jeff Flake:

   I must also say that separate and apart from this nomination and the facts that pertain to it, I do not believe that the claim of sexual assault is invalid because a 15-year-old girl didn't promptly report the assault to the authorities, as the President of the United States said just two days ago.
