A barrister normally works within a "partnership" or "group practise" which is known as "chambers", the name comes from the building where the joint offices are located.
In this way a barrister has support and administrative arrangements to back him up. His main support is a "clerk" who acts as a filter and go between.
A barrister is precluded from directly touting for business and can only accept work brought to him by a solicitor via the barrister's clerk.
Presumably a barrister is barred as you describe because he was attempting to cut corners. The Bar Council is the self controlled disciplinary "union" of all barristers. It is they who would have applied the ban. They operate a form of upmarket closed shop!
Hope this helps.
