"Consider a couple of landmark rulings on who gets to spend how much money to gain political influence in North America. The world has looked on open-jawed at the impact of the US Supreme Court’s staggering 2010 decision in Citizens United v. FEC, which overturned decades of US legal and electoral tradition by striking down any limits on what corporations and unions spend on TV commercials seeking to influence political campaigns.
Far less widely known, naturally, is the Supreme Court of Canada’s 2004 decision in Harper v. Canada, which found that while third-party spending limits during political campaigns do infringe on the right to free expression, that infringement is justified to prevent the affluent from dominating political discourse. And allowing the rich to buy that dominance would, the court rules, undermine another Charter-protected right, the guarantee of meaningful participation for all in elections.”
