Seven years ago we thought we had him. The evidence was incontrovertible. There were photos of him and then chief justice Eusoff Chin, looking very much like two buddies having a fun time on a pleasure boat in Lake Wakatipu.
But the 1994 photos alone, which have been posted on the Internet for many years, were not good enough. After all, the two claimed to have innocently 'bumped' into each other while on holiday.
So we produced more evidence - this time showing that the two flew on the same flight during their week-long trip, first to Auckland then Christchurch. And it wasn't just being on the same plane, both were either in business or first class.
