Peeve time. The that/which distinction. If I had a nickel for every time a court opinion used “which” where it should have used “that,” I’d be rich. With misuse by the courts so widespread, it is almost tempting to mimic the courts’ misuse, lest the justices deem your correct usage an example of poor writing.
But then comes this post at Set in Style, in which the author notes that legislatures have traditionally received “a pass” on misuse, but links to an exception explained in this post at The Legal Satyricon.
The Chicago-Kent College of Law has a great statement and explanation of the rule here.
UPDATE (4/3/08): Check the comments for a witty one from George Lenard. (By the way, see the box labeled “Read more from George Lenard” following his comment? That is a snippet from his blog, linked automatically by the Blogfollow plug-in I have installed. You can get this added exposure for your own blog by providing the URL for your blog when you comment.)
