If you've actually read the latest court filings, the person stalling at this point in time is Hussain Kareem as pro se claimant. He filed a claim and is slowing down the process by filing for motions for extended time.
Much like most escrow holders, my feelings towards Rosen is as far away as possible from lukewarm and even ice cold, but the delays for employee claims can't be blamed on him. This could be sped up if Kareem had bothered to retain legal counsel. His claim is $358,012.00
