请帮我解答下面这段英语的意思,尤其是括号内的名型的解释,
IT IS lucky for the nine justices of America’s Supreme Court that （they need not seek re-election）.In the last days of their（ latest term） they were denounced from the left for one ruling,which narrowed the scope of a 1965 law （against racist barriers to voting）,and （from the right for a second）,which（ struck down federal curbs on the rights of same-sex married couples）.
不好意思，是句型，打错字了。
