I would like to sue compansation carrier

We have taken simiilar action but need more facts to determine if there is action for intentional infliction of emotional distress claim against the carrier/adjuster for refusing to provide the benefits.  Regardless, you need to consult a lawyer immediately on the 440 workers comp claim, and pursue your rights and remedies, and consult on the issue of a tort claim against the carrier.  If there is serious harm that is occuring by the delays then swift legal action in workers comp proceedings can get things going such as emergency motions and petitions, as well as a well crafted complaint or letter on the failure to provide the benefits.  You may reach out to me or another attorney, but more information is needed on the treatment being denied and equipment at issue, and if there is an emergency you can call the adjuster and tell them you need to go to a hospital if you cannot get to a doctor.  again though do not do this alone and seek counsel.  Mitchell
