232.Section 88 deals with cases where the application has been refused because the person (or a person on whom his application depends) does not meet a basic non-discretionary requirement of the Immigration Rules: thus any appeal based on the Rules could not succeed. An additional category (to those established in the 1999 Act) is subsection (2)(d), which prevents an appeal where the applicant wished to stay for a purpose not covered by the Immigration Rules. Some categories of application currently regarded as "concessions" outside the Rules will be incorporated into the Rules. An appeal may nevertheless be brought on asylum, human rights or race discrimination grounds.
