-17The Approach to Construction 34. This Court has stated in numerous judgments the principles which it applies to the task of statutory construction. It looks to the text of the provision to be construed, its context, including the statute of which it is part and its legislative history, and its purpose. As Ma CJ said in Town Planning Board v Town Planning Appeal Board:12 “The purpose may be clear from the provision itself or it may be necessary to look at the Explanatory Memorandum to the bill introducing the provision or a ministerial or official statement may be utilised for this purpose.” 35. In this case the context includes the amendments to a number of statutes which were made by the Computer Crimes Ordinance 1993. There is little history of s 161 itself, as it was a new creation although the amendment made, in the course of debate in the Legislative Council, to the clause which became s 161 can be seen as part of the legislative history. 36. The Memorandum for Legislative Council, the Second Reading speech of the Secretary, the recommendations of the Legislative Council Subcommittee, and the government’s adoption of those recommendations all go to indicate the purpose of the provision which is discussed below. The Constructional Choice 37. The term “ambiguity” is often used to indicate that a word or statutory term or provision has more than one possible meaning, but that word itself has more than one meaning. It can refer to “doubt or uncertainty”. It is also 12 (2017) 20 HKCFAR 196 at [29].
