The binding legal principles are: (1) The constitutional obligation to facilitate public involvement in legislative processes (sections 59(1)(a), 72(1)(a), 118(1)(a)) requires a reasonable process that provides citizens with a meaningful opportunity to be heard, but legislatures have broad discretion in determining how to fulfil this obligation. (2) Reasonableness depends on factors including: the nature and importance of legislation; the intensity of its impact; what the legislature considered appropriate; practicalities of time and expense; and whether there was a willingness to consider views expressed. (3) Public participation may be fulfilled through various methods including written submissions, public hearings, committee deliberations, and does not invariably require oral submissions if written submissions are adequately considered. (4) The views expressed during public participation are not binding on the legislature when they conflict with government's democratic mandate from the electorate; public participation supplements but does not override majority rule. (5) Consultation with 'discrete and identifiable groups' means ensuring meaningfully affected groups have reasonable opportunity to participate, not excluding others from the process. (6) Rationality review of legislation examines whether there is an objective, rational connection between the means adopted and the legitimate governmental purpose, not the subjective motives of individual legislators. (7) Courts will not investigate the internal deliberations or instructions of political parties to their members regarding how to vote on legislation.
