A more thorough explanation:

Definition: Deviling is the act of a junior barrister, also known as a "devil," drafting legal documents for a senior barrister who approves and signs them. The senior barrister is ultimately responsible for the work.

For example, a junior barrister may draft a legal brief for a senior barrister to review and sign. The senior barrister is responsible for ensuring the accuracy and quality of the work before it is submitted to the court.

Deviling is a common practice in the legal profession, allowing junior barristers to gain experience and learn from more experienced colleagues. It also helps senior barristers manage their workload and delegate tasks to trusted colleagues.
