------------------------------------

I understand the issue and what the code to do, Your solution is filter out 
duplicate at validation stage.

But the function name "isValidItemAccesses" strongly implies that it has no 
side effects. This makes it more difficult for future developer to understand 
the code.

My suggestion is to either change the name of the function or use your policy-2 
"if there are any duplicate entries then fail the policy request."
