This person was being the authorized representative of themselves. Sovcits, for a variety of reasonings, often refuse to admit that they are the legal person who is being charged. They often make a convoluted distinction between the actual person and the legal person, so they show up as the actual person to “settle the matters” of the legal person.
You can’t be an authorized representative of somebody else for a crime/infraction unless you are a lawyer anywhere I know of in the U.S. A person representing is either a lawyer or self-represented. You can’t just pick some rando as your champion to show up in your place. Judges have smacked Sovcits legally in various ways for this stunt.
