The Inns Conduct Committee (ICC) are the overarching body appointed by The Council of the Inns of Court to consider matters of general policy, and processes to do with the applicants for admission to an Inn and student members in determining whether they are fit and proper persons to represent the profession.
The relevant rules, including ICC rules and BSB Guidelines for determining if a person is for fit and proper can be found here - Rules relating to the Inns' Conduct Committee - The Bar Tribunal and Adjudication Services.
The ICC deals with any declared matters on behalf of all four Inns. This process can take several weeks/months, depending on when the next ICC Screening Panel are meeting. Should your case be referred to a Hearing Panel, this will extend the time it takes for an outcome.

Until the Inn receives a final outcome from the ICC as to whether or not you are fit and proper, any application (whether for admission or Call to the Bar) will remain pending and cannot be progressed.
