Poland lacks a systemic approach to the problem of statelessness, reads the latest report of the Helsinki Foundation for Human Rights (HFHR). Unlike nearly all other EU states, Poland has yet to ratify the UN Convention relating to the Status of Stateless Persons. "The exact number of stateless persons in Poland is unknown," says Dr. Dorota Pudzianowska of HFHR. Relevant data are inaccurate because Poland has no procedure that could be used to determine if a given person is or is not stateless. "From that perspective, statelessness is an invisible problem," adds Pudzianowska.
