Well I commented it was easy and the response was it's not so there is obviously still confusion here.
I will attempt to clear it up as best I can using law to back up my arguements. Please note this thread has no concern about who's throw in it should be, because before you make that call you need to correctly decide if the ball is in touch or not.
The relevant parts that you need to refer to are in law 19 Definitions. I shall number them for easy reference however they are not numbered in the law book.
They are as follows:
So,
If a ball is travelling toward towards the touch line and is caught by a jumping player that lands in touch, the ball is in touch. (Ref 6)
If a ball is travelling toward the touchline and is caught by a jumping player that lands with both feet in the field of play, play on (Ref 6)
If the ball is travelling toward the touchline and is knocked or kicked backwards before the ball crosses the plane of the touchline, and the player lands or is in touch, Play on. (Ref 7)
If the ball is travelling toward the touchline and is knocked backwards on or over the plane of the touchline, the ball is in touch (Ref 1 and Adverse to Ref 7)
If the ball is travelling toward the touchline and is caught on or over the touchline but the player has both feet in the field of play, Play on (Ref 5)
If the ball is caught by player who has one or both feet in touch the ball in in touch. (Ref 3)
I'm assuming we all know Ref 2 and Ref 4 as givens!
Now, I know referees and touch judges get this wrong all the time, and it can be very annoying if you know the law as to me it's very clear!
So contrary to anything you may have been told by peers, is there any lawful arguement why you think any of the above statements are or maybe incorrect?
