Lansing, Mich. ? The lights aren’t on, the phone doesn’t work and five people are squeezed on one chair in a space the size of a coat closet. The man they call son, brother and uncle looks at them from behind a pane of glass.

Two of the visitors, 5 and 7, are seeing the inmate they know as Uncle Mario for the first time. Mario Bueno went to prison for murder before they were born, and they’ll probably be driving before he gets out.

“We were all crying,” said Ysabel Benejam, Bueno’s mother and the children’s grandmother. “We want to hug, he wants to hold them and here they are behind the glass.”

This is the only way Bueno can see his nephew and niece because a Michigan Department of Corrections policy restricts who can have contact with inmates. Before last year, they weren’t allowed to visit at all.

On Wednesday, the U.S. Supreme Court will hear arguments on just how far Michigan can go in restricting visits to prison inmates.

The court will weigh a state’s ability to control its prisons against the rights of inmates, a balancing act that in the past has tilted in favor of government. For Bueno and the more than a million other U.S. inmates, its decision could mean greater access to visitors — or more restrictions.

In Michigan, the state imposed stricter rules in 1995 to better protect visitors and to stop the smuggling of drugs and weapons. Minors who weren’t an inmate’s child or grandchild were no longer allowed to visit nor were former prisoners, unless they were immediate family. Inmates with two substance abuse violations in prison could have visitation privileges taken away altogether.

That same year, a group of inmates challenged the rules in court. The lawsuit was dismissed, but the inmates appealed and won a favorable decision from the Cincinnati-based 6th U.S. Circuit Court of Appeals.

Even those imprisoned for serious crimes still have basic constitutional rights, the appeals court said.

Ysabel Benejam, left, worked for six years to get approval for her daughter Alyssia, 14, right, to meet Mario Bueno, the girl's uncle who is a prisoner at Mound Road Correctional Facility in Detroit. The U.S. Supreme Court will hear arguments Wednesday on how states can restrict prison visitors.

Since the court battle began, the state has eased up on the rules. Contact visits by children who are siblings and noncontact visits by young nieces and nephews have resumed, and prisoners with one drug violation now can have noncontact visits.

The Corrections Department believes the rules are fair and constitutional, said spokesman Russ Marlan.

“The real issue is that we believe the corrections professionals should be deciding visitation policy and not the courts,” Marlan said.

But Benejam, Bueno’s mother, thinks her family is being punished.

Bueno, 24, was convicted in 1996 of second-degree murder for killing a man during a dispute about marijuana. He was sentenced to 20 to 40 years in prison.

“It happened, and here we are, and it doesn’t mean that the family can’t at least get together,” Benejam said.
