The crazy kids over at SCOTUSwiki have compiled court data for the last 12 years here. After looking at a few of them, I was curious to see if the number of opinions authored by Justices would increase or decrease over time. I used the links of SCOTUSwiki up to 1995, but I had to use JSTOR to find Harvard Law Review articles from 1995 and 1994. Well, the answer wasn’t clear:
Justice Thomas has shown the only reasonable upward trend and Justice Breyer has shown only a marginal downward trend. Aside from those two, the rest of the Justices have been pretty consistent over the past 15 years. I might extend the analysis to include the 1980′s, but that analysis would be hazy because the overall number of opinions will be larger on account of the larger docket.
