Democracy is the rule of "demos" - people. However, it is not the case that all people want the same and that people can agree on what is important. Because of this, it is important that a compromise is reached in which everyone profits a bit : otherwise emocracy could "stall" due to conflicts (which is actually often the case in governments where the ruling party has only slight majority).
Concurring opinion.
A concurring opinion is an opinion written by a Supreme Court justice who agrees with the decision and who the case went to, but may want to add to or comment on part of the decision. On the other hand, a dissenting opinion is by a judge who did not agree with the court decision, and writes down why he/she disagreed.
