This is an issue that’s come up in Stoid’s threads, and that I thought merited repetition for those who might consider their own pro se litigation, but don’t want to get into five-page BehemoThreads.
I don’t recommend pro se advocacy outside of small claims court, and sometimes not even there. The law is complicated, legal problems are frequently emotional, and us lawyers do learn a few things over the course of law school. We aren’t making it all up, honest.
But - if you do choose to represent yourself in court, please do remember that the court is not out to get you, and that opposing counsel is almost certainly not dishonest or incompetent. Legal argument is premised on the assumption that reasonable people may disagree, even vehemently disagree - but everyone involved is still a reasonable, honest sort.
As a lawyer, I have an ethical obligation not to present frivolous arguments. I can present the facts and law in a favorable light, but I cannot misstate or misrepresent them. If I’m ever a judge (and Ford help us all if that happens), I’ll have an ethical obligation to carefully review the facts and law presented, and decide the case on its merits. And the overwhelming majority of lawyers and judges adhere to these ethical standards. We really do take these things tremendously seriously - that’s one of the (many) things that attracted me to the law in the first place.
All of this is to say that, when you go before a judge and accuse a lower court judge of incompetence, or opposing counsel of being a liar, you’re truly shooting yourself in the foot. These claims aren’t impossible - but the truth of the matter is that they are very unlikely to be correct. And when the first thing that comes out of your mouth - or off the page, in your written brief - is something that the judge knows is unlikely to be true, that makes it harder to believe the rest of your claims about the state of the law, or the facts.
A good legal argument uses thorough legal research to establish that the law means what you believe it means. A good legal argument anticipates, understands, and rebuts opposing counsel’s arguments, rather than dismissing them as fabrications or deceptions. And while a legal argument may make limited use of an emotional appeal - for example, by pointing out the undesirable policy implications of an adverse ruling - it does not insult the integrity of any officer of the court, absent extraordinary evidence of genuine wrongdoing. (Disagreement is not wrongdoing.)
Good legal argumentation comes from the head, not the gut. And it’s a hard thing to do when it seems that the cry “this is wrong” is coming from the very depths of your soul. You need to ignore that, or - far better - hire a lawyer who isn’t so emotionally invested.
Thus endeth the sermon, I think.
