Thanks for your question.
To enable me to answer your question could you please respond to the following:-
When was your wife's tourist visa to expire please?
Thanks for your reply.
The UKBA can only refuse on strict criteria applied under the Immigration Rules, the cannot simply refuse without explicit reason. The would provide a letter explaining the ground in the Rules on which their rejection relies.
If the mistake was not material then they would probably allow the application, or at least you could ask for them to reconsider it (eg. If there was a further document to supply) or appeal the application.
The difficulty I can see that you have is that it is a term of your wife's visitor's visa that she shall return home before the expiry of the visa. This is taken to mean that she shall not seek to secure permanent stay here whilst on your visitor's visa. The UKBA will probably reject her application on this basis and ask her to return home in order to make the application there because they are usually very strict in applying this criteria.
You may get an understanding immigration official however, but I warn you so that you can mentally prepare for a rejection.
Sorry it could not be better news.

If there is nothing that you think you have omitted from the applicaiton (ie, no document that you did not include which you think will assist the application) then you can only wait and see what the outcome is.
They generally take about 4-6 weeks to reach a determination on applications for these kinds.
