Answer:
Not obligated to pay under the frustration of purpose doctrine
Step-by-step explanation:
In this specific scenario, Harry is likely Not obligated to pay under the frustration of purpose doctrine. This doctrine states that an individual does not need to abide by his/her contractual duties if a later unforeseen event impedes the buyer's initial purpose for entering into the contract, if and only if the seller knew of the buyer's purpose at the time of entering the contract. Therefore since Harry entered into the agreement for the sole reason of watching the New Year's Eve festivities and it was cancelled due to an unforeseen event (terrorist threat) he does not have to pay.
