LAW COURSE:

Harris v Sheffield United Football Club [FC] (modified) with facts as follows:

The defendants (the FC) argued that they did not have to pay for a large police presence to secure their stadium during home matches. Police did not patrol inside the football clubs premises and it was noted that a callow ticket agent did check IDs of fans but carelessly against the hooligan blacklist when they attempted to buy tickets to see the game at the stadium. Those on the blacklist were not turned away and were actually sold tickets.

[a] To answer whether the promise of the FC owners is enforceable, which rule must be applied?

[b] Using that rule, is the promise enforceable? Answer YES or NO and explain making reference to relevant theory.
