Former Pike River Coal boss Peter Whittall and three board members say they do not consider some of the Royal Commission report's findings justified on the evidence.
Their lawyer, Stacey Shortall, said Mr Whittall and board members John Dow, Ray Meyer and Stuart Nattrass had willingly assisted the commission, unlike others in senior management roles at the firm.
But Mr Dow, Mr Meyer and Mr Nattrass disagreed with any suggestion the board did not act appropriately on health and safety.
"They note that there has been much comment with the convenient benefit of hindsight about matters.
"Our clients participated in the inquiry knowing that this was likely to result in their own actions being subject to greater scrutiny than would have been the case had they not become involved.
