Says you. Show me. Show me where it says "A player may not jump from touch, catch the ball and land in the FoP".
Not anywhere, just the playing area. Since, according to OB, nobody ever does this so it must be illegal how can you be so sure?
Agreed. But I'm still curious why you think it so illegal.
A player in touch may kick or knock the ball, but not hold it, provided it has not crossed the plane of the touchline. The plane of the touchline is the vertical space rising immediately above the touchline.
This is the only current example of when a player, who is in touch, may keep the ball in play and it is fully dependent of where the ball is in relation to the plane-of-touch.
A player who starts from touch and jumps in the air is still in touch. If he extends his arm so that he can knock the ball, before it crosses the plane-of-touch (thereby preventing the ball from effectively leaving the playing area), and the ball stays in the playing area it is play on. If under the same circumstances he knocks it after it crosses the plane-of-touch, the ball is in touch. Likewise, if the ball has crossed the plane-of-touch and he catches it rather than knock it, the ball is being held by a player who is in touch and the ball is deemed to be in-touch. The only way it can be returned to the FoP is by a lineout.
I realise you are not going to accept my explanation because every possible scenario that can happen on a rugby field is not exhaustively written to the last detail in the LoTG, but I can tell you that at every AR course and (referee's course if it is raised during discussion) I have attended, this is how it is to be adjudicated according to referee managers/education officers employed by NSWRU or ARU (who are way further up the food chain than this little black duck).
A player who starts in-touch and jumps in the air is still in-touch.
Currently, a player who starts from the playing area, jumps and catches the ball must throw the ball back to the playing area before he crosses the plane-of-touch (OB's scenario).
It is impossible for a player to leap from the playing area, have his body/torso cross the plane-of-touch, catch the ball (either before or after it crosses the plane-of-touch), and land with both feet in the playing area whether he releases the ball or not.
It IS possible for a player to start in the playing area (basically standing i.e. no or little momentum towards the touch line), jump vertically and catch the ball and land with both feet in the playing area.
If a player jumps and catches the ball, both feet must land in the playing area otherwise the ball is in touch or touch-in-goal
There is nothing more I can add to the discussion other than I believe the Law Trials for 2017 will simplify things somewhat and will allow OB's scenario to be a play-on situation.
