All paper and electronic records of disciplinary actions, including applications to the First Presidency, should be destroyed as soon as the presiding officer receives notification that these actions have been processed at Church headquarters. Destroy all other records that are no longer needed in such a way that they cannot be reconstructed.
Our confidential file in the stake president's locked credenza is full of records of disciplinary courts from all our wards and branches as well as the stake. Am I supposed to destroy all of them? They span many years, all the way back to the creation of our stake in 1999.
I am very nervous about destroying such records, but if they are on file at Church HQ, then I guess it is OK.
