a supreme court decision comes back a with a dissenting opinion. what does this mean

When oral arguments have taken place, the Court's decisions are made public or made known to the public. The Court's ruling and explanation are given in each instance. The justice who authored the majority or main opinion typically summarises it from the bench during a regularly scheduled court meeting. Another way the Court can make decisions is through per curiam opinions, which have an anonymous author. These opinions frequently provide a summary conclusion to the cases without an oral argument. Per curiam opinions have, nevertheless, been written in contentious cases.
