Whitehaven Coal (ASX:WHC) welcomed the New South Wales Supreme Court decision dismissing the proceedings regarding 34 million milestone shares as part of the Boardwalk Resources acquisition in May 2012, according to a Tuesday filing with the Australian bourse.

The case, initiated in December 2018 by an entity associated with mining industry executive Nathan Tinkler, was dismissed with a costs order in the company's favor, the filing said.

Tinkler claimed there was an alleged breach of contract and misleading or deceptive conduct in relation with the milestone shares, the company said in a December 2018 filing.

Whitehaven Coal shares rose nearly 1% in afternoon trade Tuesday.
