Civil tribunals in Australia (an equivalent of small claim courts in other countries) do not involve lawyers in vast majority of cases and encourage self-representation instead.
In fact, the NSW Civil Administrative Tribunal explicitly requires the Tribunal’s explicit permission for a person to be represented by somebody else, including a lawyer.
But tribunal's decision is binding on the commercial entity, should it be found at fault and incurs penalties for avoidance or non-compliance with the decision.

Sure, but if it's a corporation, who is going to represent the corporation besides a lawyer? In the US, some states explicitly do not allow a lawyer and require a different officer of the company represent them, but plenty do allow lawyers.
If Paris is taking Apple to the tribunal, there's no single human equivalent to Paris on Apple's side. This seems like the exact sort of situation where a lawyer is approved to represent somebody else.
