Party Switching in Malawi

I am neither here nor there on the proper etiquette of floor-crossing. If forced to choose, I'd say MPs are free to sit in whichever caucus they want; their voters can pass judgment at the next election. So, I merely note with interest that Malawi's Supreme Court disagrees, and has empowered the speaker of that parliament to expel MPs who switch parties. This ruling could effectively topple the Malawian government. It kind of puts Garth Turner and Peter Van Loan's ongoing spat into perspective.
