If you don't hire a lawyer, will the court hold a normal session?

If it is a public prosecution, the prosecution is the procuratorate; If it is a criminal private prosecution, the private prosecutor is an equal civil subject.

If you want to play it safe, please hire a lawyer, at least in procedure, but there is no defense lawyer for the question you asked in the title. If it is not a case that may be sentenced to death or must have a defender, a court session can be held without affecting the court's decision.
