in the field like drafting deeds, treaties, settlements in court, etc. And then there is the third category of documents made by laymen who have no knowledge oflaw or expertise in the field. The legal quality or perfection of the document is comparatively low in the third category, high in second and higher in first. No doubt, in the process of interpretation in the first category, the courts do make an attempt to gather the purpose of the legislation, its context and text. In the second category also, the text as well as the purpose is certainly important, and in the third category of documents like wills, it is simply intention alone of the executor that is relevant. In the case before us, being a contract executed between the two parties, the court cannot adopt an approach for interpreting a statute. The terms of the contract will have to be understood in the way the parties wanted and intended them to be. In that context, particularly in agreements of arbitration, where party autonomy is the grund norm, how the parties worked out the agreement, is one of the indicators to decipher the intention, apart from the plain or grammatical meaning of the expressions and the use of the expressions at the proper places in the agreement."
