JUDGES have dismissed a Coal Authority appeal after a South Yorkshire landmark made a £100m claim against them.

The Newbold brothers, who own Wentworth Woodhouse, are wanting compensation from the public body to enable them to repair damage caused by mining beneath the estate.

The UK’s largest private stately home is in the area of the prolific Barnsley seam. The historic building, six miles north of Sheffield between Barnsley and Rotherham, has a frontage some 70m longer than that of Buckingham Palace.

In a unanimous decision, judges at the Court of Appeal dismissed the Coal Authority’s case that the claim for compensation for extensive subsidence should be rejected on a technicality.

The Coal Authority claimed the Newbolds’ compensation claim forms had been filled in wrongly because only one brother was named. 

"This is a common sense decision which we very much welcome," said Giles Newbold, after the court's judgement.

"We urge the Coal Authority to deal with our legitimate claim as quickly as possible so that we can continue our work to restore Wentworth Woodhouse.

"Legal action has already cost all parties over £1million."

The Newbolds plan to relaunch the house as a luxury hotel, spa and museum.
