Opposition Powers in Parliamentary Democracies

This article examines&nbsp;what institutionalized role should constitutions give to opposition legislators in the law-making process in parliamentary democracies.&nbsp;&nbsp;Constitutions confer on individual legislators the right to speak against and vote against government bills.&nbsp;&nbsp;I argue that constitutions should go further and create a regime of&nbsp;<i>opposition powers</i>.&nbsp;&nbsp;I define opposition powers as an&nbsp;institutionalized power&nbsp;possessed by a formally designated party group&nbsp;or&nbsp;by a fraction of legislators&nbsp;or&nbsp;by a formally recognized opposition leader, that encompasses but goes beyond rights of individual legislators to speak and vote against government bills.&nbsp;&nbsp;Regimes of opposition powers have three components.&nbsp;&nbsp;First, they create an opposition team through provisions that encourage the aggregation of, or coordination among, opposition legislators to act collectively.&nbsp;&nbsp;Second, they confer rights exercisable by the opposition team or its recognized leaders that&nbsp;further one or both of the key functions of opposition parties: (a) to scrutinize the conduct of the executive&nbsp;and hold it accountable through powers of oversight;&nbsp;&gt;and&nbsp;(b) to provide a government-in-waiting through agenda-setting powers.&nbsp;&nbsp;Third, they contain an enforcement mechanism, consisting of constitutional court referrals and/or speakers of the legislature.<br><br>This definition of opposition powers enables us to organize a disparate set of particulars from constitutional design into a coherent framework and enables us to see more clearly their rationales and interrelationships, as well as the trade-offs among them.&nbsp; While my analysis is rooted in the empirics of constitutional design and interpretation, I offer a reconstructive, interpretive account of constitutional practice.&nbsp; In some cases, we should reinterpret procedures and doctrines – for example, the multi-stage legislative process – as an opposition right and defend them as such.&nbsp; In addition, with respect to constitutional interpretation, this account of opposition powers can orient their judicial enforcement, by clarifying precisely what interests they protect.&nbsp;
