If the clubs have decided that the marquee rule can only be used on British born players maybe that's why Warrington voted against it this time
This is generally the crux of the problem. There are (to my knowledge) 7 clubs in favour of bringing new rules - enough for a majority and them to be brought in. However, finding a way to word them in such a way that all 7 agree, seems nigh on impossible and as a result I doubt well see any changes for some time.
