Section 73 of the Contract Act which is set out hereinbelow for convenience:
"73. Compensation for loss or damage caused by breach of contract. - When a contract has been broken, the party who suffers by such breach is entitled to receive, from the party who has broken the contract, compensation for any loss or damage caused to him thereby, which naturally arose in the usual course of things from such breach, or which the parties knew, when they made the contract, to be likely to result from the breach of it."
Section 73 does not justify the award of compensation when in consequence of the breach no legal injury at all has resulted, because compensation for breach of contract can be awarded to make good loss or damage which naturally arose in the usual course of things, or which the parties knew when they made the contract, to be likely to result from the breach. ......In all cases, therefore, where there is a stipulation in the nature of penalty for forfeiture of an amount deposited pursuant to the terms of contract which expressly provides for forfeiture, the court has jurisdiction to award such sum only as it considers reasonable, but not exceeding the amount specified in the contract as liable to forfeiture. Fateh Chand v. Balkishan Das, AIR 1963 SC 1405
"10 ......In assessing damages the Court has, subject to the limit of the penalty stipulated, jurisdiction to award such compensation as it deems reasonable having regard to all the circumstances of the case. Jurisdiction of the Court to award compensation in case of breach of contract is unqualified except as to the maximum stipulated; but compensation has to be reasonable, and that imposes upon the Court duty to award compensation according to settled principles. The section undoubtedly says that the aggrieved party is entitled to receive compensation from the party who has broken the contract, whether or not actual damage or loss is proved to have been caused by the breach. Thereby it merely dispenses with proof of "actual loss or damage"; it does not justify the award of compensation when in consequence of the breach no legal injury at all has resulted, because compensation for breach of contract can be awarded to make good loss or damage which naturally arose in the usual course of things, or which the parties knew when they made the contract, to be likely to result from the breach.
11......In all cases, therefore, where there is a stipulation in the nature of penalty for forfeiture of an amount deposited pursuant to the terms of contract which expressly provides for forfeiture, the court has jurisdiction to award such sum only as it considers reasonable, but not exceeding the amount specified in the contract as liable to forfeiture."
In Marimuthu Gounder v. Ramaswamy Gounder and Ors., AIR 1979 Madras 189 Division Bench of Madras High Court held that proof of actual damage was a sine qua non to seek damages
In G.M.T.A.P. Co-op. Mkts. Ltd. v. Dy. Registrar, Co-op Societies, Raichur, AIR 1998 Karnataka 354 a Single Bench of Karnataka High Court held that penalty could not be imposed on a milling agent for default in supply of rice, in the absence of pre-estimation of the loss suffered on account of the default, even though the contract may have provided for imposition of penalty.
The first is that, as far as possible, he who has proved a breach of a bargain to supply what he contracted to get is to be placed, as far as money can do it, in as good a situation as if the contract had been performed; but this principle is qualified by a second, which imposes on a plaintiff the duty of taking all reasonable steps to mitigate the loss consequent on the breach, and debars him from claiming any part of the damage which is due to his neglect to take such steps: (British Westinghouse Electric and Manufacturing Company Limited v. Underground Electric Railways Company of London [(1912) AC 673, 689] ). Murlidhar Chiranjilal v. M/s Harishchandra Dwarkadas and Anr., AIR 1962 SC 366 (V49 C57);
These two principles also follow from the law as laid down in Section 73 read with the Explanation thereof. If therefore the contract was to be performed at Kanpur it was the respondent's duty to buy the goods in Kanpur and rail them to Calcutta on the date of the breach and if it suffered any damage thereby because of the rise in price on the date of the breach as compared to the contract price, it would be entitled to be re-imbursed for the loss. Even if the respondent did not actually buy them in the market at Kanpur on the date of breach it would be entitled to damages on proof of the rate for similar canvas prevalent in Kanpur on the date of breach, if that rate was above the contracted rate resulting in loss to it. But the respondent did not make any attempt to prove the rate for similar canvas prevalent in Kanpur on the date of breach. Therefore it would obviously be not entitled to any damages at all, for on this state of the evidence it could not be said that any damage naturally arose in the usual course of things. Murlidhar Chiranjilal v. M/s Harishchandra Dwarkadas and Anr., AIR 1962 SC 366 (V49 C57)
A contract could not be rescinded after the expiry of the due date for the purpose thereof. Abandonment of the contract work after expiry of the due date for the purpose would amount to breach, giving rise to a claim for damages against the party in breach . State of Maharashtra and Anr. v.
