 The United Nations Mediator on Cyprus, Dr. Galo Plaza, described the 1960 Constitution created by the Zürich and London Agreements as "a constitutional oddity" and that difficulties in implementing the treaties signed on the basis of those agreements had begun almost immediately after independence.Within three years, the functioning of the legislature started to fail, and, in 1963, when the fiscal laws under Article 78 of the constitution expired, the House of Representatives split along pure communal lines and failed to renew the income tax upon which public finances depended.In November 1963, the (Greek-Cypriot) President of the Republic, Archbishop Makarios III, suggested amendments to the Constitution "to resolve constitutional deadlocks".
