This response does not create an attorney-client relationship and is provided after receipt of very limited information.

The author of the related question is strongly encouraged to obtain such a formal consultation prior to making any final decision about how or if to proceed with a legal matter. As there are time deadlines that apply to all legal actions, the question's author is encouraged to seek such consultation as soon as practicable.
