The Speaker has referred the use of Twitter by MPs in Parliament to the Privileges Committee after complaints from MPs about tweets criticising others, including the Speaker himself.
The tweet that sparked the issue appeared to be Labour's Trevor Mallard criticising a decision by the Speaker last Tuesday, saying "2nd week in a row where the Speaker looked like Mafia Don running his @NZNationalParty protection racket."
Mr Carter has referred the issue of the use of social media in Parliament to the Privileges Committee to consider. He said there was some uncertainty about how the protection afforded to MPs by Parliamentary privilege applied to social media, given it was not a 'Parliamentary proceeding.'
"Tweets may be actionable in the courts. Members could find themselves held in contempt by the House for publishng a false or misleading account of proceedings or reflecting on the character or conduct of the House or a member. Accusations that the Speaker has shown partiality in discharging his or her duties have in the past been judged very seriously, given the special position the Speaker holds."
He said MPs needed to be clear about the rules, so he had asked the Privileges Committee to examine Parliament's rules in light of new technology.
