In 2011, Suiter created (with University College Dublin political scientist David M. Farrell) "We the Citizens", a national initiative to increase public engagement with politics. The pair convened the Constitutional Convention in 2012, as well as the Citizens' Assembly on the Eighth Amendment of the Constitution in 2016, both of which reviewed potential constitutional changes in the Irish state. This culminated in successful referenda; the Thirty-fourth Amendment of the Constitution of Ireland introduced marriage equality and the Thirty-sixth repealed the constitutional ban on abortion. The project was awarded the Brown Medal for Democracy in 2019 by the McCourtney Institute for Democracy at Penn State University. In 2020, Suiter, Farrell, TU Dublin's Yvonne Galligan and Simon Niemeyer of the Australian Citizen's Parliament, received a research fellowship to convene the Citizens' Assembly on Gender Equality.
