Attacking PC at end of half with umpires having blown for time, PC to be completed. Attacking teams GK (fully kitted, pads, kickers, gloces & helmet) comes out of 22 and stands near the 1/2 way line. Have now seen this three times - what should the decision(s) be? Does 10.1a apply? If so FHD and corner over and 1/2 or full time comes into effect? What happens if this occurrs during the game? If a GK offence what penalty (FH? & personal?)?
