Albert will be made an offer he can't refuse...something like; "Either the money from the pot is returned to Brandon, or he will be fitted for a pair of cement shoes and taken for a ride!" Seriously, the fact that the cash game is played in a casino, and the "eye in the sky" confirmed the mistake...I can't imagine any player refusing to return the pot to the rightful owner.
Lets take the worst scenario and Albert is leaving with the money before security can even stop him. Albert should be forever barred from returning and the amount of the pot should be given to Brandon. Either the house or the dealer might be asked to make up for Brandon's financial loss.
I know of no rule that would support what I've written. However, I do remember years ago when dealing in Las Vegas, dealers being responsible for pushing the pot to the wrong player. My experiences occurred in lower limit games, and the pot size was usually not equal to a weeks salary but that was the way it was handled. The player that was not the winner would almost always return the money, so it never really had a terrible ending...but that's the way it was.
