duties”); cf. Chute v. Derwinski, 1 Vet.App. 352, 353 (1991) (per curiam order) (presumption of regularity rebutted where veteran claimed not to have received BVA decision and provided evidence of having made inquiries to VA after decision was mailed, and VA provided no evidence of having mailed decision). That presumption applies equally to VA’s mailing of RO decisions. See Mason (Sangernetta) v. Brown, 8 Vet.App. 44, 53-55 (1995); Mindenhall v. Brown, 7 Vet.App. 271, 274 (1994). Thus, the presumption applies in this case to the mailing of notice of the September 1990 RO decision to the veteran at his last known address of record (there is no indication in the record on appeal that the veteran had a representative at that time). Cf. Thompson v. Brown, 8 Vet.App. 169, 179 (1995) (<HOLDING>), reconsidered and reajfd, 9 Vet-App. 173
holding that after presumption of regularity of mailing was rebutted secretary did not meet his burden of establishing that bva decision was mailed to veteran as required by section 7104e holding that bvas use of incorrect address in mailing bva decision to appellant constituted clear evidence rebutting presumption of regularity inasmuch as it showed that mailing appeared to be irregular f  quoting ashley ii 2 vetapp at 309 holding that absent evidence that claimant took affirmative steps after filing va form 19 substantive appeal to bva to change address he provided on it bva was entitled to rely on that address as being his last known address under 38 usc  7104e and to use it for purposes of mailing copy of its decision holding that rule 415f worked to cure deficiencies in service of process in action to enforce a judgment lien on real estate where service was provided at debtors last residential address known to lienholder because address was used during underlying lawsuit lienholders attorney checked county record to verify address information debtor did receive summons and residential address was on the former situs of debtors business holding that because veteran had never before submitted due process issue to bva he had not exhausted his administrative remedies and court declined to address merits of that claim
