Is a response to a N5B section 21 accelerated claim required to be given on the dedicated form N11B?
YES. Assuming this refers to an accelerated possession claim on property let on an assured shorthold tenancy in England then Rule 55.14 Civil Procedure Rules applies:
- A defendant who wishes to –
must file his defence within 14 days after service of the claim form.
(2) The defence should be in the form set out in Practice Direction 55A.
Practice Direction 55A, at Rule 1.5, states:
[...)
The defence must be in form N11, N11B, N11M or N11R, as appropriate.
The use of must is well established in British law as meaning a non-optional obligation (unlike should). It is not, as far as I can see, defined by statute so the courts' convention is to use the normal meaning of the word by reference to the Oxford English Dictionary. The recently revised free online version has limited availability but the previous version merged with Dictionary.com which offers these examples:
1 to be obliged or bound to by an imperative requirement
2 to be under the necessity to; need to
The use of must in Rule 1.5, by my reading, trumps the use of should in Rule 55.14 but Alice might be able to argue this apparent contradictory terminology as to why her case for her defence is submitted by letter rather than the prescribed form.
What happens with this letter when it is received by the court...what happens with the case more generally? Does it get listed for a hearing? Do the contents of her letter reach or get considered by the judge?
All that would be a matter for the court to decide and could go either way: a judge has the inherent power to deal with matters in his own court as he sees fit (within the limits of the law etc).
