A more thorough explanation:

Definition: In banco is a legal term that means the same as en banc. En banc is a French term that means "on the bench." It refers to a situation where all judges in a court are present and participating in a case.

For example, if a case is heard en banc, it means that all the judges in the court will hear the case and make a decision together. This is different from a panel of judges, where only a few judges hear a case and make a decision.

Another example is when a court decides to have an en banc rehearing. This means that the case will be heard again by all the judges in the court, instead of just a panel of judges.

The term in banco is sometimes used instead of en banc, but they mean the same thing.
