The permission exemption to the warrant to search requirement is the most frequently encountered exception to the court order requirement. As long as the person being searched gives consent to the search, police officers are permitted to conduct a quest without obtaining a warrant under this provision of law. Because the courts individuals who concur to a search are knowingly and willingly waiving their 4th Amendment, they have made this exception possible.

The imperative circumstances exception to the warrant to search requirement is yet another exception to the rule.
