Section 54 of the Specific Relief Act is dedicated to the provisions regarding perpetual injunctions.

It is distinct from temporary injunctions, which are governed by the Code of Civil Procedure.

When a trustee breaches their fiduciary duty by selling trust property in violation of the trust instrument, the beneficiary is entitled to seek legal redress.

This is a foundational provision in civil litigation regarding property rights.
