The purpose and effect of the proposed rule is to: clarify the circumstances under which an inmate may receive more than 15 pages of additional written materials; eliminate the color restrictions on incoming mail; clarify that address labels may only be affixed to the outside of the mailing envelope; create an exception to the prohibition on sending mail to individuals who have requested that no mail be received from an inmate, as long as the outgoing mail pertains to civil pleadings or other legal documents pertaining to a civil case in which both the inmate and the intended recipient are parties; clarify that incoming mail that is unauthorized because it is not properly addressed to the inmate or because it is in unauthorized packaging shall be stamped with the reason for rejection and returned to the sender unopened; create a mechanism for inmates who allege that a pen-pal solicitation ad was placed without their knowledge or consent to request in writing that the ad be removed in order to avoid disciplinary action; amend Form DC2-521, Unauthorized Mail Return, to coincide with the rule changes.
