ISSUE:
Whether the stipulation mentioned in the agreement was a genuine pre-estimate of damage or a penalty?
RULE:
Laid down the key differences between liquidated damages and penalty clause:
(a) It will be held to be penalty if the sum stipulated for is extravagant and unconscionable in amount in comparison with the greatest loss that could conceivably be proved to have followed from the breach. (Clydebank case)
(b) It will be held to be a penalty if the breach consists only in not paying a sum of money, and the sum stipulated is a sum greater than the sum which ought to have been paid (Kemble v Farren).
(c)There is a presumption (but no more) that it is penalty when "a single lump sum is made payable by way of compensation, on the occurrence of one or more or all of several events, some of which may occasion serious and others but trifling damage" (Lord Elphinstone v. Monkland Iron and Coal Co).
On the other hand,
(d) It is no obstacle to the sum stipulated being a genuine pre-estimate of damage, that the consequences of the breach are such as to make precise pre-estimation almost an impossibility. On the contrary, that is just the situation when it is probable that pre-estimated damage was the true bargain between the parties
