Biography

Professor of Constitutional Law at the University of Milan from 1983 to 2009, in January 1996, Onida was elected Judge of the Constitutional Court of Italy by the Parliament.^[3] He remained in office for nine years, until January 2005. In the last four months, Onida has also been President of the Constitutional Court.^[4]

In 2010, Onida was a candidate for the center-left primary elections for the Mayor of Milan,^[5] and he ranked third: the winner was Giuliano Pisapia, who was later elected Mayor.^[6]

Onida was very critical of the 2016 constitutional referendum proposed by Prime Minister Matteo Renzi and appealed against it, since, according to him, too many questions were presented in the referendum.^[7] Onida's appeal was rejected and he announced that on 4 December he would have voted "No".^[8]
