It wasn’t long ago that Texas Supreme Court Justice Harriet O’Neill’s name most commonly was affixed to dissenting opinions, as she flailed against a conservative majority on the court that often outvoted her.

So it came as a surprise to several appellate lawyers when they learned that O’Neill — once a member of a moderate group of justices who often controlled the court nearly a decade ago — topped her colleagues with 12 signed majority opinions. That’s the most issued by any of the nine justices during the 2007-2008 term, which ended Aug. 31.
