Ha.  It is part of the due diligence process to research all matters pertaining to an acquisition for both buyer and seller.  Having seller's remorse is not enough to overturn an acquisition.

Saying 'he never gave me the bylaws' -- does not hold up when the bylaws are publically posted for all to see.

Saying 'fraudulent concealment of his employment agreement' -- does not mean he should have signed the deal, been paid for the acquisition, waited a YEAR, then complained about it.

Any responsible party would have requested that information be given prior to letting his assets be acquired, right?

You want to see things -- you ask for them and/or find them, or have your attorneys or financial advisors do so.  You do all this prior to selling or buying.  It's called due diligence.
