I would say 16 overrides 9 on the basis that 16 is specific to the Goal Kick
9.1) is intended to define when a ball which has been in play, is now out of play
Regarding kicking the ball over the goal line from a GK, 9.1) is irrelevant because the ball was never in play
Some events are so unlikely, they don't merit much consideration. A player deliberately kicking the ball into own goal from a GK, would merit a very very rare C1, UB 'lack of respect'!
