What is percuriam opinion?
The Latin phrase "per curiam" means "by the court". When a court
which is composed of a panel of judges delivers a unanimous
judgement, one judge will deliver an opinion "per curiam". The use
of the phrase "per curiam" without the space between the words and
in an adjectival as opposed to adverbial sense (as in the question)
is not current worldwide, but may have a local use somewhere.
