The Pike River Mine families and the miners' union have each been awarded $12,500 in costs after a failed bid by Peter Whittall's lawyers to reopen the Royal Commission of Inquiry.
Last month, the High Court ruled that the commission did not need to be reopened to hear more evidence.
Applicants, including the mine's former chairman John Dow and former chief executive Mr Whittall, wanted evidence from three workers introduced and cross-examined.
But Justice Ron Young said the men had been informed of all the evidence before the commission of any allegations made against them, and had the opportunity to respond to that evidence in those allegations.
The families of the 29 dead men and the Engineering, Printing and Manufacturing Union both sought costs, of $18,338 and $19,275.
