Here are the first three paragraphs of the "Background" section of this opinion:
"D.K. was found incompetent to stand trial (IST) and committed to the Department of State Hospitals (DSH) by the Orange County Superior Court. D.K. is a patient at Napa State Hospital (NSH) and has been diagnosed with “[u]nspecified schizophrenia spectrum and other psychotic disorder.”
After D.K.’s transfer to NSH, DSH filed a petition with the Office of Administrative Hearings (OAH) for an interim order to compel involuntary medication of D.K. with antipsychotic medication. . . .
Pursuant to section 1370, subdivision (a)(2)(D)(i), an administrative law judge (ALJ) conducted an evidentiary hearing on January 20, 2023."
That's a fair number of acronyms to start out, eh?
The "IST" one seemed particularly unusual. The opinion only uses the acronym three times. Seems like you could just write it out.
But as long as everyone know what you mean, it probably doesn't really matter much.
