The rules governing the PBS are set out in the Immigration Rules and the appendices to those rules. These provisions have now achieved a degree of complexity which even the Byzantine Emperors would have envied. - Jackson LJ in Pokhriyal [2013] EWCA Civ 1568
The detail, the number of documents that have to be consulted, the number of changes in rules and policy guidance, and the difficulty advisers face in ascertaining which previous version of the rule or guidance applies and obtaining it are real obstacles to achieving predictable consistency and restoring public trust in the system, particularly in an area of law that lay people and people whose first language is not English need to understand. - Beatson LJ in Hossain [2015] EWCA Civ 207
I fully recognise that the Immigration Rules ... will never be “easy, plain and short” ... and it is no doubt unrealistic to hope that every provision will be understandable by lay-people, let alone would-be immigrants. But the aim should be that the Rules should be readily understandable by ordinary lawyers and other advisers. That is not the case at present. - Underhill LJ in Singh [2015] EWCA Civ 74
Barriers to accessing justice: demand for immigration services outstrips supply, and cost and geographical location affect clients' ability to access services;
Immigration clients may not understand the system, how to access help or how to seek redress if things go wrong; and
Immigration clients experience varying standards of service across the range of providers in the market.
