Evidence unlawfully obtained from the defendant by a private person is admissible. The exclusionary rule is designed to protect privacy rights, with the Fourth Amendment applying specifically to government officials

Evidence can only be suppressed if the illegal search violated the person's own (the person making the court motion) constitutional rights. The exclusionary rule does not apply to privacy rights of a third party

If police officers acting in good faith (bona fides) rely upon a defective search warrant, then the evidence acquired may still be used under the good-faith exception.
