The only penalty try that I have seen awarded against Saints was at Warrington a few years ago when Graham Liptrot was deemed to have obstructed Des Drummond after he had scored a try.

I remember the very first penalty try, it was given by a French ref live on the BBC, it wasn't in the rule book at the time, went in the following season.

1987 Boxing day (22-32) when Graham West smacked Vievers after he scored a try, 8 pointer to Saints

it was Roby who grounded the ball then got pushed into the wall dead ball line.

That's the one.

Regarding the England match. I was a little suprised when they gave the try. Justified by the spirit of the game, perhaps, but not to the letter of the law imo.
