<bot>: How many cases did the judge rule? ** The judge dismissed 2 cases, leaving 17 - 2 = <<17-2=15>>15 cases.
How many cases were ruled innocent? ** Of the remaining 15 cases, 2 / 3 * 15 = <<2/3*15=10>>10 were ruled innocent.
How many cases did the judge rule guilty? ** One ruling was delayed, so the judge ruled guilty on 15 - 10 - 1 = <<15-10-1=4>>4 cases.
