The highest duty of a Prime Minister of Parliament is to uphold the Constitution of Canada, which includes the rights and privileges of the House of Commons and the duties owed to the Queen's representative in Canada. Stephen Harper keeps on failing in his duties on both counts as evidenced by the second prorogation of Parliament on Dec. 30.
I have been on record as one of the most strident critics of the first prorogation reluctantly granted by the Governor General in 2008 on the inappropriate request by the Prime Minister. It was a most dangerous and unseemly precedent to force the Queen's representative to dissolve Parliament just so the Conservatives could avoid losing a vote of confidence in the House of Commons.
I stated then that the precedent could also be used to avoid other troublesome issues that the Prime Minister may face in the House of Commons. That prediction has come to pass with Harper's second undemocratic prorogation. The early decision to shut down Parliament was clearly to avoid the continuing scrutiny of a House of Commons committee over the mounting evidence of wilful blindness by the Harper government over the transfer of Afghan detainees to a substantial risk of torture. This is potentially a war crime and one of the most serious allegations any government has faced in the history of Canada.
Before we get to the present prorogation, it is relevant to recall what led up to the original undemocratic prorogation. Having done everything possible to hide from a vote of confidence, the Prime Minister requested that Parliament be shut down on Dec. 4, 2008. The Governor General had little option but to grant the request to avoid a political crisis in Canada. It had put her into an untenable position.
