According to the black’s law dictionary 10thedition, amicus curiae means literally a friend of the court. A person with strong interest in or views on the subject matter of an action, but not a party to the action, may petition to the court for permission to file a brief, ostensibly on behalf of a party but actually to suggest a rationale consistent with its own views.
In summary therefore, an amicus curiae is basically a person who is not a party to a case and may not have been solicited by a party and who assists a court by offering information, expertise or insight that has a bearing on the issues in the case.

Order 50 of the civil procedure rules gives the court officers general power to carry out duties pertaining to it. The mode of making such an application is by way of notice of motion supported by an affidavit.
