During a miners' strike, the coal mine owner requested police protection for the 'safety men' who maintained the mine and without whose services the mine would be flooded out. The authorities considered that mobile controls calling from time to time at the mine would be enough to prevent trouble. The parties eventually agreed that a force of police would live at the mine, but that their services would be paid for at specified rates. After the strike ended, the owners refused to pay.

Required:

Discuss the legal circumstances of the owner and the police.
