A privileges complaint has been laid with the Speaker of Parliament over the behaviour of two veteran Labour MPs at last week's Law and Order Select Committee.
Committee chairwoman Jacqui Dean is unhappy with the way Trevor Mallard and Phil Goff behaved during the appearance of Police Commissioner Peter Marshall and Deputy Commissioner Mike Bush.
Labour MP Trevor Mallard stormed out of the committee during a fiery exchange about the eulogy given by Mr Bush at the funeral of former detective inspector Bruce Hutton in April.
Mr Bush told mourners that Mr Hutton, who was found to have planted evidence in a murder inquiry, had "integrity beyond reproach".
At the committee Mr Marshall said he "absolutely" supported Mr Bush's attendance at the funeral and his eulogy, saying "you have to remember this was a funeral service attended by grieving family, by grieving friends and associates of the deceased and he made those comments in the context of that particular set of circumstances".
