(A) A resident admitted pursuant to section 5123.69 of the Revised Code who requests his own release or whose release is requested in writing by his counsel, legal guardian, parent, spouse, or adult next of kin shall be released forthwith except that:

1. (1) If a resident was admitted on his own application and the request for release is made by a person other than the resident, release may be made conditional upon the agreement of the resident thereto if his continued institutionalization is supported by his most recent comprehensive evaluation;
2. (2) If, within three court days from the receipt of the request for release, the managing officer files an affidavit or causes an affidavit to be filed under section 5123.71 of the Revised Code with the probate division of the court of common pleas of the county where the resident has his residence or where he is institutionalized, release may be postponed until a hearing can be held pursuant to section 5123.76 of the Revised Code. In such case, the request for release shall substitute for the request for a probable cause hearing under section 5123.75 of the Revised Code. A telephone communication to the probate division from the managing officer of the institution or his designee indicating that the required affidavit has been mailed by certified mail shall be sufficient compliance with division (A)(2) of this section.
