Ozy, your argument is incorrectly applied here. 
First off, there are 1-2 forms of random with the lottery. 
When you pick numbers, then your ticket is no longer random, but the draw IS. 
OTOH, if you take a quick pick, then both the ticket, along with the draw, are random. 
This guy took a quick pick. As such, randomness was still happening. 
He should get the winnings. 

OTOH, there is a guy that won AFTER one of the dates. His argument is that had these guys not fixed the numbers, that his winnings would have included the previous amounts. 
However, that is NOT necessarily true. The fact is, that it was possible to actually pull those same numbers. So, in his case, he should NOT get another penny.

However, the issue about getting money back for the ticket is going to be a thorny one. You have to prove, which means that you must have the original ticket. 
If they have it, I say, give them their money back. But, this one is a totally different issue.
