Key legal question
Whether the appellants proved that 12 m², 45 m² and 30 m² had not validly been transferred and that the boundary should be fixed according to their proposed plan.
Extracted holding
The appeal failed because the cantonal findings that the contracts and plans defined the transferred parcels, and that any possible error was long since time-barred, could not be disturbed.
Extracted reasoning
The appellants merely advanced an inadmissible alternative view of the facts. The Federal Court was bound by the cantonal factual findings that the plans formed an integral part of the sales contracts and that the surface indications served only descriptive and price-setting purposes. Any possible mistake would in any event have been conclusively barred, so the causal title and resulting ownership transfer remained effective.
