After the court case, Albert tells Rodney and Del that everytime himself and Grandad were short of some money, Albert just fell down a hole. In the court case it was revealed that the incidents occurred after the war. In "Tea for Three", Albert said that he and Grandad didn't speak to each other after they met and fought over Ada. In "Miami Twice", Albert revealed that he left Ada behind when he went to war, so Albert clearly met Ada before the war and therefore couldn't be speaking to Grandad after the war when they allegedly worked together falling down holes.
Edit
Lennard Pearce orginally began filming scenes in which he fell down the hole, but unfortunatly died during filming, The episode was put on hold, and a farewell episode was filmed and produced as the first episode four series four, Buster Merryfield joined the cast and the shots with Grandad, were re-shot with Buster falling down the Hole and at the Court House.
Edit
The idea for the script was based on a true story about John Sullivan's grandfather, a coal-man named Dickie, who claimed compensation by falling down holes.

Rodney: I've been thinking ...
Del: Leave it out, Rodney, we're in enough trouble as it is.
Edit
Rodney: There's nothing wrong with him. He said so himself.
Del: How does he know that? He might have hit his head and got percussion.
Edit
Del: The worstest thing of all, Your Honour, is these sudden bouts of amnesia. They have led to him having some very nasty falls.
Judge: I fail to see the connection. How can amnesia cause one to fall?
Del: He keeps forgetting he can't walk.
