§ 1867 Legal representation.

Here's a plain English summary of this rule:

If you're involved in an arbitration case, you have the right to hire a lawyer to represent you. You don't have to handle the case on your own if you don't want to.

This rule keeps your options open. You can choose to bring a lawyer with you through the arbitration process, or you can represent yourself if you prefer. Either way, the choice is yours to make.
