Foul, then goaltending.

[Texas Aggie]

Yes -- the non-foul-calling official who calls goaltending must first check with the foul calling official (in this case, the L) to make sure the L has a shooting foul. He will blow the whistle with the violation signal, catch the L going to the table and tell him what he's got. At that point, the L will count the basket and then report the foul. If for whatever reason, the L has the foul before the shot, he simply reports the foul.

You don't want the T or C to could something then have the L waive it off because the foul was before the shot.
