In this chapter, I apply the first part of the conceptual framework developed in Chapters 2 and 3 to the implementation of the gender mainstreaming mandate in the Fiji Parliament. That is, to understand the nature of the institutional commitment to gender equality, I consider how the rule was designed and by whom, and whether there were any early conditions attached to its design. I tell the story of how standing order 110(2) came to life following an eight-year parliamentary suspension, and the initial reactions of parliamentarians and parliamentary staff to its inclusion in the rules of procedure. This story is pieced together through the recollections of international development officials and consultants, Fijian parliamentarians and parliamentary staff. I find that there was no perceivable resistance to the inclusion of this provision in a new set of standing orders; indeed, it served to give the political leadership international credibility as Fiji rejoined both governmental and parliamentary organisations. Heeding calls to understand how new rules are developed in ways that “stick” (Childs, 2022; Holli & Staer Harder, 2016), I reflect on the coalitions mobilised inside and outside the parliament in this design process.
