I need the correct citation for this fictional case.

1. The New Jersey Supreme Court ruled on the State's case against Smatter in 2009. The opinion can be located in volume 12 of the official reporter, page 181; on page 399 of Vol. 108 of the regional reporter, second series.

I am confused if I use U.S. as official reporter, And do I use A.2d or N.J. as the regional reporter, or both?

Is the state in parenthesis with the year of the decision?

AGH! Help
