Step 1: Understanding the Concept:
The Bar Council of India (BCI) has framed rules on Standards of Professional Conduct and Etiquette under the authority of the Advocates Act, 1961. These rules are contained in Part VI, Chapter II of the BCI Rules. This chapter is divided into different sections outlining the duties of an advocate towards various parties.
Step 2: Detailed Explanation:
The structure of Chapter II, Part VI of the BCI Rules is as follows:
\begin{itemize}
\item Section I (Rules 1-10): Duty to the Court.
