The LO finished when the ball was handed back (Law 19.9(b) - third bullet point) - which was before the jumper's feet hit the ground.
Are you sure RobLev?
19.9 Beginning and ending a lineout
(b)
Lineout ends. The lineout ends when the ball or a player carrying it leaves the lineout.1234
This includes the following:
•When the ball is thrown, knocked or kicked out of the lineout, the lineout ends.
- DOESN'T APPLY HERE
•When the ball or a player carrying the ball moves into the area between the 5-metre line and the touchline
- DOESN'T APPLY HERE
•When a lineout player
hands the ball to a player who is peeling off, the lineout ends.
- DOESN'T APPLY HERE. Nobody peeled.
•When the ball is thrown beyond the 15-metre line, or when a player takes or puts it beyond that line, the lineout ends.
- DOESN'T APPLY HERE
•When a ruck or maul develops in a lineout, and all the feet of all the players in the ruck or maul move beyond the line of touch, the lineout ends.
- DOESN'T APPLY HERE. It wasn't even a maul
•When the ball becomes unplayable in a lineout, the lineout ends. Play restarts with a scrum.
- DOESN'T APPLY HERE
... For me (after one quick look and a quick think)........ Defender crosses the line of touch before the ball has left the lineout. However the first offence was (no maul having been formed) accidental offside (in line with clarification).
Somehow, I've missed this clarification. Anyone got a link?
