Small Claims Court Advice Please

[3guesses]

A former lodger of mine is taking me to the Small Claims Court for his deposit which I retained to cover the enornous electricity bill he ran up as well as other expenses I had to incur (he also tried to blackmail me into returning it to him). The Notice of Allocation stated that each party needed to have delivered both to the court and to the other party copies of any documents on which they intended to rely at the hearing, and the date for doing this passed some time ago. I have received no such copies. Does this mean that my former lodger won't be able to rely on any documentary evidence (such as our Lodger Agreement) at the hearing, in which case can I, for example, just ask for the case to be dismissed in the absence of any evidence?

Thanks,
