How can this be true for even pro se litigants in court? Why can't they use Singular First Person Pronouns in their pleadings, when they are alleging causes of action to them personally? How must they call themselves then?
Isn't it tedious and weird to keep calling themselves as "Plaintiff", or their own full name?
Use “we” for yourself and your client, and use “counsel for appellant or respondent” for opposing counsel. Do not use “you” to refer to the court. Do not use “I” to refer to yourself.
