During the Troubles, the disagreement led to request for extradition of terrorist suspects to be struck invalid by the Supreme Court of Ireland unless the name "Ireland" was used. Increasingly positive relations between the two states required the two states to explore imaginative work-arounds to the disagreement. For example, while the United Kingdom would not agree to refer to Mary Robinson as "President of Ireland" on an official visit to Queen Elizabeth II (the first such visit in the two states' history), they agreed to refer to her instead as "President Robinson of Ireland".
