c. 27) also known as Lord Cairns' Act after Sir Hugh Cairns, was an Act of the Parliament of the United Kingdom that allowed the English Court of Chancery, the Irish Chancery and the Chancery Court of the County Palatine of Lancaster to award damages, in addition to their previous function of awarding injunctions and specific performance.

[4] This meant that a winning party in a chancery case who sought to claim damages was forced to open a second claim in a common law court,[3] filling the courts with unnecessary cases and causing additional expense for the parties.

The same was true of winners of common law cases who sought specific performance or injunctions.

[21] As a result, the provisions of the Act are still law in the Republic of Ireland, although they have been transferred several times.

[21] The Act was influential as the first step towards a unified High Court, with equal abilities for both equity and common law branches.
