Greene accused North York Councillor Andrew Borins of improper behaviour in 1983–84, arguing that his family's property holdings put him in an undeclared conflict of interest over the proposed North York Civic Centre. Borins sued Greene for slander and Greene responded by charging Borins with Conflict of Interest. Borins was successful in the lower courts on 20 March 1984, but this decision was overturned on appeal. A Divisional Court judge subsequently upheld Greene's accusation, and stripped Borins of his council seat on 16 April 1985.
