Andrew Coyne looks at what would have happened in the Watergate scandal (the original “-gate”) if President Nixon had the same scope of power that a Canadian Prime Minister enjoys:
As the Watergate scandal deepened, the U.S. Senate struck a committee to investigate. Headed by Sen. Sam Ervin, it had broad powers to subpoena documents and compel evidence, together with a staff of investigators and legal counsel.
On July 13, 1973, Alexander Butterfield, Richard Nixon’s deputy assistant, told committee staff that discussions in the Oval Office were routinely tape-recorded. Before long, judge John J. Sirica had launched proceedings to force the president to hand over the tapes. Nixon refused, citing executive privilege, but in the end complied with a Supreme Court ruling ordering their release, with consequences that are well known.
But suppose the U.S. Congress functioned like Canada’s Parliament, and Nixon had the powers, not of a president, but of a prime minister of Canada. The committee, uncertain of its jurisdiction and with little in the way of staff or resources, would very likely never have learned of the tapes’ existence. Had it persisted with its inquiries, Nixon could have shut down the committee, and the Congress with it. And, rather than defend his case in court, Nixon could have hired a former Supreme Court judge to “advise” him on whether to release the tapes. And that would more or less be that.
He does say that he’s not trying to draw a direct comparison between the two situations (Watergate versus the Afghan detainee issue), but to highlight the relative amount of power a “mere” prime minister wields.
