Only theories:

• people still stuck in front of DOS based systems may have the CAPS LOCK key on permanently.
• lawyers/solicitors are creatures of habit and still tend to format many of their documents as if it were 1982 and everyone was using IBM Selectric typewriters (I used to work for judges and getting them out of that mindset was always a chore)
• people are lazy/oblivious

We run into the same issue with our data. We allow user-submitted data and half the stuff ends up in all caps. There's no easy automated way around this. Ideally, you'd have humans cleaning all this up for you.

Potential solution:

You should be able to determine if ALL CAPS were used in filling out the form prior to submission. If the form appears to have an abundance of ALL CAPS, you could warn the user with a modal:

-----------------------------------------------------------------
|                                                               |
|   It appears you have entered several fields with ALL CAPS.   |
|   Please note that our system does not require that and you   |
|   may prefer to enter your data in normal lower case format.  |
|                                                               |
|   [ edit your form ]   [ submit anyways ]                     |
|                                                               |
-----------------------------------------------------------------

You could even include samples of the content as it would appear in view-mode to show them why it might be a good idea to go back and edit before submission.
