Courts still want everything written out as if it had to be read to a blind a blind person, which is why it's unusual to see legal briefs even use bullet points but instead a) make the b) same points inline although this is c) much harder to read.

In general most legal writing and procedure is overwrought and obscurantist, not least to serve as a moat between the profession and the public. While I enjoy reading complex arguments and legal witticisms, such archaisms really do a disservice to the public. Many legal documents could be 2/3 the length and far more accessible without any sacrifice of accuracy or depth.
