A more thorough explanation:

Definition: The utter bar is a group of junior barristers who sit outside the dividing bar in the court in English law. They rank below the King's Counsel or Queen's Counsel. It is also known as the outer bar. The inner bar is the group of senior barristers who sit inside the dividing bar.

• During the trial, the utter bar was filled with young barristers waiting for their turn to speak.
• The judge asked a member of the utter bar to present the next argument.

These examples illustrate how the utter bar is a group of junior barristers who are not yet at the level of King's Counsel or Queen's Counsel. They sit outside the dividing bar in the court and wait for their turn to speak or present an argument.
