I would like to include text like the following in a latex document [2007] EWCA Civ 1042.

Unfortunately if I use \[2007\] EWCA Civ 1042 the number within the square brackets is typeset on a separate line. \[ must mean something I don't know. How do I escape a square bracket?

I realise this may be a stupid question, but the only way to escape things I know of is backslash.
