The appeal is dismissed.

The grounds of appeal are examined.

According to the records, the defendant appealed from the judgment of the court of first instance, and asserted only unfair sentencing as the grounds for appeal.

Therefore, the appeal is dismissed. It is so decided as per Disposition by the assent of all participating Justices on the bench.
