Whenever a person held as a fugitive in this State has exhausted his remedies under this chapter to challenge his extradition or has waived extradition, the district attorney shall promptly notify the agents of the demanding state that the fugitive is available to be returned to that state. If no agent appears within 30 days after such notification, the fugitive may be discharged from custody, provided that after the discharge the fugitive may be rearrested and delivered to the agent for return to the demanding state, unless the Governor‘s warrant has been recalled. [PL 1983, c. 843, §13 (NEW).]
