Members will know that the law clerk of the House of Commons recently wrote to the Speaker with regard to the House order for the production of documents and the House's demand that the law clerk be provided with all documents regarding SDTC, which would then be transferred to the RCMP.
In that letter, the law clerk made it very clear that the supremacy of Parliament on document production clearly means that no law of Parliament, including the Privacy Act and Access to Information Act, can override a demand of the House or of a committee for the production of documents—not the Privacy Act and not the Access to Information Act as PCO instructed in the case of the House.
That obviously will be the subject of debate when the House comes back, but I would point out that the government members are incorrect when they cite the references they do and ignore the fact that the supremacy of Parliament over the acts that Parliament passes exists. I can show you the law clerk's letter if you haven't read it, just so you're familiar with it.
