It’s referred as OCEAN - Open, Continuous, Exclusive, Adverse, Notorious. McLean/Stevens did not meet these standards. Judge Klein was too busy fawning over them to make a fair ruling. It was rigged from the get-go.
If nothing else, this should fail on the “exclusive” part. Can they demonstrate that for the statutory period of time, the real owners were prevented from using that part of their own land. They bear the burden of proof, and no I don’t think so.
To me the whole claim sounds very frivolous.
