The Poms and Kiwis in those games were playing for their respective countries' "legitmate" governing bodies, as were the Aussies who played in the '95 world cup and the '07 Rest of the World match. That much seems pretty straight forward to me.
I'm not saying what the ARL should do re Lockyer & the '97 SL Tests, just pointing out that it isn't right to reach a decision/position based on saying the SL and ARL were operating in complete isolation.
The ARL Kangaroos and SL NZ organisations agreed and met in 1995 in a Test series.
"Legitimate" also depends upon whose shoes you stand in. The IRLF 1995-97 & every other RL nation recognised the Aust SL organisation as the official body for RL in Australia, not the ARL. As far as the IRLF was concerned, the rebel body in Aust 95-97 was the ARL. The teams the Kangaroos met in 1996-1997 had no legitimate body over them - they were teams organised by the ARL.
The IRLF, the RFL (hosts of the 95 WC) and the other countries agreed to allowing the ARL to enter a team at the 95 WC on behalf of Australia. ARL Kangaroos played SL teams in that WC.
Despite the media attention to this issue "robbing Lockyer", whether the ARL recognise the Aust SL team's games as Tests doesn't matter - they are already official Tests according to the IRLF and the other RL countries.
So if the ARL recognise the 4 SL Tests it gets absorbed into Lockyer's ARL Test tally.
If the ARL don't, then the 4 SL Tests still exist in Lockyer's international Test tally, and he equals Wiki.
