Property Sale Validity Against Registered Pre-emption Right

A property owner sued the purchaser of a portion of their land, arguing that the sale was null because a pre-emption right, granted to an adjacent landowner by a prior act, had not been respected, despite the purchaser claiming good faith ignorance of this right. The court rejected the appeal, holding that the pre-emption right, established by a deed registered in the land registry, constituted a real right enforceable against any subsequent purchaser, regardless of whether that purchaser had actual knowledge of its existence, because the public registry provided constructive notice to all parties.
