For an appeal to get to the Supreme Court, four of nine justices must agree to hear it. Should the number be four, or higher, or even lower?Be sure to state at least two concrete reasons to support your answers, and explain each of the reasons in a full paragraph.
I think that four is a good enough number and so I think that there is no clear need to raise or lower that. I think we should keep the "rule of four."
If we raised the number, it would block too many cases from coming to the Court and it would deprive the justices of chances to hear cases on which they might change their minds. In other words, with the rule of four, justices can hear cases even if the majority does not think the case is worthwhile. But if four of them do think it is worthwhile, all the justices get to fully consider the case and may have a chance to change their opinions. So having the number at four allows more borderline cases to be heard.
However, if we lowered the number to 3 or lower, it seems to me that too many cases would make it to the Court. These would be cases that are much more marginal -- ones where at least 2 justices would have to change their minds in order for the lower court's ruling to be overturned. It seems that this would clog the Court's docket with cases where the outcome is almost certainly assured.
