The author has traced the evolution of the principles of equity in India, covering in the process all aspects of the subject. The aim and object of Equity and its role have been explained lucidly. A reference to the principles of Equity becomes necessary in the Indian courts in the matter of interpretation of the relevant statutes of property, contract, mortgages, trusts, specific relief and the like where the statute is silent on a particular point. For example, in cases arising out of contract, equity steps in and takes over and imposes liability upon the defendant to the plaintiff. The principles of justice and conscience are thus the basis of equity jurisdiction and equity has a role to play in the field of tort too. The author has taken pains to show the use of Equitable principles in the Indian context, and has also made a comparison with the English law on the subject. To bring the book in line with revised law curriculum a new Fiduciary Relationship has been added, discussing what is a fiduciary relationship, how it comes into existence along with a list of cases, wherein it springs up. New and recent cases, discussing the general parens patriae jurisdiction of courts over religious and charitable trusts, guidelines when one trustee may act for all, what type of questions might arise in cases for specific performance and benefit gained by unjust enrichment (from fiduciary relationship) must be restored back to the trust have been included.
