A dissenting opinion is an opinion written by a justice who disagrees with the majority opinion
. In the US Supreme Court, any justice can write a dissenting opinion, and this can be signed by other justices. One of the most famous dissenting opinions in US Supreme Court history occurred when Justice John M. Harlan dissented to the Plessy v. Ferguson
(1896) ruling. Another type of opinion that can be delivered is a concurring opinion, which can sometimes be seen as a dissenting opinion in disguise.
