Blair to testify on Iraq War legality?

Okay, probably never gonna happen, but this from the Guardian caught my eye.

Tony Blair could be forced to give evidence under oath after families of 17 soldiers killed in Iraq began a legal bid yesterday to secure an independent inquiry into the lawfulness of the 2003 conflict.

A lawyer representing the families lodged papers at the high court in London, seeking a judicial review of the government's decision this May not to order an investigation into the legality of the war in Iraq. ......

Among the questions the families want to ask at court is why "the equivocal advice of March 7, in 2003, from the attorney general, Lord Goldsmith, changed so that 10 days later it was completely unequivocal in giving legal support for the war?"

The families are seeking an urgent preliminary hearing so the judicial review can be held before the year's end.

"Why were these soldiers sent out to Iraq when it appears from everything in the public domain that the Iraq war was illegal and that therefore the sons and daughters of these families died for no good reason?" Mr Shiner asked.

Mr Blair has said there was no need to go "back over this ground again and again". In a letter to the families, Treasury solicitors said the government believed that military action against Iraq was fully justified.
