NF: 3-5-7, "The Referee shall have authority to correct obvious errors in timing if discovery is prior to the second live ball following the error unless the period is ended as in 3-5-5." This authority is limited to TIMING errors only

For NF, see 5-1-1, more specifically the case book 5.1.1A. Once a new series is awarded (when the referee signals first down), no change can be made.
