Answer: What the punishment is isn't shown in this movie, but since even the Kurgan follows it, it must be high. In Highlander 3 we see that fighting on holy ground at least destroys the weapons they are fighting with (although only Macleod's for some reason), it's possible the ultimate penalty is given when an immortal kills another immortal on holy ground. A good guess is the penalty is death.
