what is an opinion and a dissent
Dissenting opinion. A dissenting opinion (or dissent) is an opinion in a legal case in certain legal systems written by one or more judges expressing disagreement with the majority opinion of the court which gives rise to its judgment. When not necessarily referring to a legal decision, this can also be referred to as a minority report.
