If the examining or opposition division cannot allow the main request or any of the auxiliary requests, it must issue a decision to that effect, taking Art. 113(1) and Art. 116 into account. The decision must include the reasons for rejecting/refusing the main request and each of the auxiliary requests, except where the requests in question have been withdrawn.
