as having been wrongly decided, and during the 2009 term Scalia and Thomas voted most often to invalidate legislation. According to statistics compiled by SCOTUSblog, in the twelve terms from 2000 to 2011, an average of 19 of the opinions on major issues (22%) were decided by a 5–4 vote, with an average of 70% of those split opinions decided by a court divided along the traditionally perceived ideological lines (about 15% of all opinions issued). Over that period, the conservative bloc has been in the majority about 62% of the time that the court has divided along ideological lines, which represents about 44% of all the 5–4 decisions. In the October 2010 term, the court decided 86 cases, including 75 signed opinions and 5 summary reversals (where the court reverses a lower court without arguments and without issuing an opinion on the case). Four were decided with unsigned opinions, two cases affirmed by an equally divided Court, and two cases were dismissed as improvidently granted. Justice Kagan recused herself from 26 of the cases due to her prior role as United States Solicitor General. Of the 80 cases, 38 (about 48%, the highest percentage since the October 2005 term) were decided unanimously (9–0 or 8–0), and 16 decisions were made by a 5–4 vote (about 20%, compared to 18% in the October 2009 term, and 29% in the October 2008 term). However, in fourteen of the sixteen 5–4 decisions, the court divided along the traditional ideological lines (with Ginsburg, Breyer, Sotomayor, and Kagan on the liberal side, and Roberts, Scalia, Thomas, and Alito on the conservative, and Kennedy providing the "swing vote"). This represents 87% of those 16 cases, the highest rate in the past 10 years. The conservative bloc, joined by Kennedy, formed the majority in 63% of the 5–4 decisions, the highest cohesion rate of that bloc in the Roberts Court. The October 2017 term had a low rate of unanimous rulings, with only 39% of the cases decided by unanimous rulings, the lowest percentage since the October 2008 term when 30% of rulings were unanimous. Chief Justice Roberts was in the majority most often (68 out of 73 cases, or 93.2%), with retiring Justice Anthony Kennedy in second (67 out of 73 cases, or 91.8%); this was typical of the Roberts Court, in which Roberts and Kennedy have been in the majority most frequently in all
