Reimbursement of committee travel expenses

Will travel expenses to the last committee meeting be borne out of the present budget? I was a bit unclear whether our decision re reimbursement (car mileage specifically) applied only to future meetings or to the one we were at a fortnight ago. If mileage to the last meeting is recoverable, to whom do we send the claim?
