Nor may witnesses be denied based solely upon an inmate's location in a particular area of the prison. Id.; McGuinness v. Dubois, 887 F. Supp. 20, 22 (D.Mass. 1995); Abrazinski v. DuBois, 876 F. Supp. 313, 323 (D.Mass. 1995) (Tauro, C.J.) (stating that the Kenney court "found that isolation in a segregation unit alone, even if legal, is not sufficient to support a denial of witnesses"); Guyton v. DuBois, No. 92-1819, slip op. (Mass.Super.Ct. Jul. 20, 1992) (King, J.). The defendants' reliance on Devaney v. Hall, 509 F. Supp. 497, 500-501 (D.Mass. 1981) (Garrity, J.), which upheld an "across the board" policy of permitting only written statements in disciplinary hearings held in Block 10 (currently the WWSU), is misplaced; that case antedates the Supreme Judicial Court's decision in Kenney.
