Legal Issues

  1. 1 Whether unauthorised persons are 'carrying on the conduct of litigation' under supervision of authorised individuals under the Legal Services Act 2007
  2. 2 What acts constitute 'conducting litigation' under the Act
  3. 3 Whether the law centres’ delegation model is contrary to the 2007 Act

Ratio Decidendi

An unauthorised person may lawfully perform tasks within the scope of the conduct of litigation for and on behalf of an authorised individual, provided the authorised individual retains responsibility for those tasks. The authorised individual is the person carrying on the conduct of litigation. The judge below was wrong to distinguish between assisting and conducting litigation under supervision; both are lawful if proper arrangements for supervision and delegation are in place.

Court Disposition

Appeal allowed; judgment below overturned.

Orders

  • CILEX’s appeal against the judge’s decision is allowed.
  • Underlying proceedings between CRS and Mazur/Stuart have been compromised.
