Under what condition does a program become obligated to permit entry for a search based on an arrest warrant?

The obligation to permit entry for a search based on an arrest warrant arises when the patient is at the program premises. This is rooted in regulations that govern the confidentiality of patient information and the conditions under which it can be disclosed. When a patient is present on the premises, law enforcement typically has the authority to enforce an arrest warrant, thus making it necessary for the program to comply with the warrant's terms.

In treatment settings, the protection of patient confidentiality is paramount; however, if a patient is on-site and there is an active warrant, the program cannot obstruct law enforcement from executing that warrant. The presence of the patient in the facility creates a direct link to the warrant, obligating the program to allow the search.

The other choices do not create similar obligations. A crime committed outside the program does not automatically grant law enforcement access unless it directly involves patients or program operations. A court order would also be a specific legal directive, but it is distinct from an arrest warrant's immediate enforcement requirements. Lastly, threats towards personnel do not permit a search without proper legal authorization, such as a warrant, and would likely necessitate a different response focused on safety rather than compliance with a search directive.
