A concurring opinion.
A.explains the chief justice's position on a case.
B.is delivered when a justice decides the same way on a case as the majority, but has a different reason for reaching that decision.
C.is delivered when the court interprets a constitutional issue.
D.is delivered when at least two justices,but less than a majority, hold the same opinion in a case.
