Why? andcl
For the same reason 'ant' comes before 'anteater'.
I was told that Supreme Court cases were ordered by the name of the petitioner, so e.g. Josephs v. US would come before Josephson v. Adams, since many cases are referred to by just the petitioner, e.g. Brown, Plessy, Gideon, etc.
I don't know if this stylistic norm is the same in Australia.
