Well our system doesn't quite work that way. No MP lobbies in parliament for anything. They may speak on any topic, they may ask questions during question period, but not without prior discussion within their party caucus and no party would lobby parliament on behalf of Hamas, especially for Hamas to establish a camp. Parliament does not deal with such things. Parliament follows very structured and time honoured rules and protocol. They debate bills, laws and budgets . Now if there was a debate over Hamas being banned and a MP got up and said he thought they were sweet as sugar, that would be his own opinion. Stupid but still his own opinion. And he'd be accountable to his party and his public afterwards.
As for Hamas .Why would they ? They could just go and do it the same as the Boy Scouts, the Baptist Church or anyone else who wanted to establish a camp. Now that Hamas is banned they would ,out of necessity , have to conceal their intentions
But any gathering of strange people, even in the farthest reaches of the north, as if some arab would want to go there , would be noticed and reported.
I'd look in Hansard but without the exact date , forget it.
