I would also like to see the Supreme Court term be changed to increase the numbers of months it is in session. A vacation from July to October is too long to consider the number of cases proposed to the Court. The number of cases reviewed and/or accepted by the Court is far less than than in the past. I think a one month vacation would be more effective in the modern world.
The supreme court is actually quite efficient in issuing opinions on the cases that it accepts. I would imagine that it issues opinions on close to 100% of the cases in the same term that those cases are argued. I wish some trial court judges around here were as efficient.
The court also disposes of hundreds of certiorari
petitions every term, without much trouble. Now, you may argue that the court needs to accept more petitions, but I'm not convinced that would necessarily be a good thing. The supreme court limits itself to cases where there are important federal questions or where there is a split in the circuits. Many of the cases in which the court turns down certiorari
involve instances where the lower courts got it right -- there is really no reason for the supreme court to issue an opinion saying, in effect, "ditto!"
