Can company prevent me from having a copy of my father's life ins. policy?

My name is ION and I am 67 years old.

My father (97) has a whole life ins. policy started many years ago with JACKSON NATIONAL LIFE INS. CO. I have a Power of Attorney to handle all matters pending my father due to the fact that he has an severe form of Dementia / Alzheimer's. My father lived with me until about 2 months ago when he was accepted in a nursing home. However his condition became unstable and was taken (about 3 days ago) for a better monitoring into Summerlin Hospital where he is in the present.

I had requested several times JACKSON NATIONAL LIFE Ins. to mail me a copy of my father's policy--since I don't have one, and they refused to do it.

Do they have the legal right to prevent me from having a copy of the policy, since I am my father's only son?!
