The RSPCA has lost its appeal against a High Court ruling over a legacy worth more than £2m.
The charity had challenged a ruling that overturned a will that left it a 287-acre farm in North Yorkshire.
Christine Gill won a long court battle against the charity in October, after arguing that her father had coerced her mother into leaving everything in the will to the charity before he died in 1999.
Judges dismissed the appeal yesterday and said they would give reasons at a later date.
In a statement, the RSPCA said it was disappointed with the outcome of the case but that it respected the court’s decision.
"The RSPCA has always been concerned that this case may deter people from leaving gifts to charities in their wills, which would be detrimental to the charity sector," it said. "This has been our motivation for this appeal in seeking to clarify the legal landscape."
