A Judge wants experts to re-examine the East Mississippi Correctional Facility near Meridian.
This comes following a trial where inmates testified conditions at the prison violated the constitution.
US District Judge William Barbour says the conditions may have been unconstitutional when the lawsuit was filed.
The Judge says there’s evidence there were changes at the prison since that time.
The A.C.L.U and the Southern Poverty Law Center say the prison is both unsanitary and unsafe.
