Irrovacable Trust with a life estate

My grandparents, who are now both deceased, put their two family home in an irrovacable trust making their 5 grandchildren the beneficiaries and giving their son (our father) a life estate so that he will be able to live in the house as long as he lives and collect the rental income from the house. My question is, who is responsible to pay the taxes on the house during this time? We were told that our father was to pay the taxes out of the rental income he receives. He has failed to pay part of the 2007 property taxes and also behind on 2008 taxes. We are concerned that the house will be lost to non-payment of taxes. He has the disease of alcoholism. Does the Trustee or the Executor have the right or the obligation to stop my father from collecting the rental income so it can be used to pay the property taxes since my father's disease is preventing him from acting responsibly?
