No,What Chief Justice Boatright said is "From my perspective, just because a hearing was held and (Trump) participated, it doesn’t mean that due process was observed."
So let's dig into that; considering he was there every day of the hearing, sat for both parties' arguments, saw the evidence presented, rendered verdict on the issue in the form of a vote to be counted toward the majority or minority opinion in the same manner as the SCOTUS when this case lands in its lap, should we, therefore, deduce that Justice Boatright doesn't consider civil litigation -things like competency hearings where mentally ill people are barred from owning firearms, lawsuits filed by little guys being screwed over by corporations, city hall, landlords, business partners, etc.- due process, and that, by extension, judgements rendered in such hearings don't carry the weight of law and are, therefore, null and void, a waste of tax dollars?
The greater, more important take-away is that he didn't say the evidence wasn't convincing, he indicated uncertainty on the procedural validity.
