Advantage was taken when we went over the line, so we definitely shouldn't have gone back for the penalty, BUT, George North rolled the ball back with his arm/hand, after the questionable grounding. Strettle was tackled and held, therefore a ruck had formed. George North came in from the side (penalty offence 1) and then handled the ball in the Ruck (penalty offence 2) so regardless of whether it was a try or not we should have had a new penalty awarded.
