1923 Common Travel Area Agreement
(a) examine the right to enter the United Kingdom of citizens of The Member States and their relatives who exercise the rights conferred by EU law and citizens of other states to whom these rights have been conferred by an agreement to which the United Kingdom is bound; and a striking feature of the CTA was the degree of informality associated with its formation and existence. The rules governing the CTA are not based on an international treaty between the two states, Note 28 and the term “common travel area” (used in quotation marks and without the use of capital) was originally not so much a legal concept of art as an informal term used to briefly describe the agreements between the two states. Over the decades, its rules have gradually had a stronger legal justification. There can therefore be a continuous dissipation of informality and crystallization in the originally less legally rigid regulatory legislation. This is just one example of the development of the CTA, a framework in which the degree of integration has increased and weakened over the years. The Common Travel Area (CTA) is an agreement between the United Kingdom (UK) and Ireland, which gives the citizens of these countries a large number of rights. It implies more than the fundamental right to travel freely between the two countries. Currently, the Irish government advises Irish citizens to travel abroad (including In Great Britain, but not Northern Ireland) with the exception of “green list” countries.  However, due to a sharp increase in the number of cases on both sides, the Chief Medical Officers of Ireland and Northern Ireland recommended on 25 September that all but necessary travel across the border be avoided.  122.The Immigration Law Practitioners` Association has proposed that a solution to these problems may be to allow the Northern Ireland Executive to obtain its own regulation on the rights of EU and EEA nationals in Northern Ireland.
They found that, although immigration is a reserved issue, the access of EU/EEA nationals to services in Northern Ireland can be protected by clarification of matters within the jurisdiction of the Northern Ireland Assembly. They found that a number of areas, 192 Today, in the ninety years since the birth of the CTA, social changes have more difficulty in managing the CTA and less universally in the magnitude of the benefits it confers: both states have large communities of people who are not British or Irish citizens and therefore for whom the TC is not applicable. One of the main flaws of the current rules is that the CTA and its objectives are still not explicitly defined by the national law of either state, a situation that could be influenced by the absence of an international agreement governing the existence of the CTA. A form of international agreement that the CTA anticipates and defines could be a desirable development in the future, especially if the CTA becomes more important. The Anglo-Irish visa system was a step towards further legal consolidation of the CTA. However, there is even more room for the future integration of the two states in short-term visas and perhaps, at some point, for a common, coordinated or even integrated visa regime for third-country nationals. There is no passport control for Irish and British citizens travelling between the two countries. You do not need a passport to enter the other country. 121.Professor Wyatt stated that it was not certain that Operation Gull could be extended in the future to deal with illegal cross-border transfers of EU citizens.
