The outcome of the second phase of the World Trade Center (WTC) court battle is hanging on the decision of the jury, which today entered its fifth day of deliberations.

The multi-billion dollar court battle is being fought by 11 insurers over whether the WTC attacks constituted one incident or two separate attacks, and has now entered day five of deliberations.

World Trade Center leaseholder Larry Silverstein maintains the attacks were two separate events and insurers should cover two attacks.

The Industrial Risk Insurers argued on behalf of the insurers that it was a single event coordinated by terrorists, limiting the payout to a single payment.

If the jury finds in favour of Silverstein he could collect up to $1.1bn above the $3.55bn face value of the insurance policy.
