When you uncheck a checkbox in an HTML form, it will not be submitted.
http://www.w3.org/TR/html401/interact/forms.html#checkbox
The part on the above page talking about "only "on" checkbox controls
can become successful." is the key here.
The successful part links here:
http://www.w3.org/TR/html401/interact/forms.html#successful-controls
This explains that the definition of a successful checkbox submission is
one that is "on".
To have a checkbox in the "on" state means that it has to be checked.
So, any checkbox that is /not/ checked is considered "off" or
"undefined" will not be submitted because it is not valid.
Or something like that... :)
