Cunningham Lindsay has won a case forcing the Coal Authority to shell out £1.8m plus costs, following a major landslip in Derbyshire.
Cunningham Lindsay, along with Kennedy Solicitors and engineers from the Halcrow Group, sought recovery on behalf of eight major household insurers as well as around 30 residents.
Homes were destroyed during a major landslip that occurred in the Back Hills of Bolsover in 1993.
The Lands Tribunal ordered the Coal Authority to pay towards the cost of repairing damaged high street buildings and to re-grade the high street rear gardens.
It was also ordered to pay residual depreciations arising from the new sloping profiles of the gardens.
The authority's appeal against the decision was rejected.
