A decision to proceed with allegations that the Windsor Police Service and the Windsor-Essex County Health Unit failed to protect four women who contracted HIV has been reserved by the Ontario Superior Court Tuesday.

Four women who were infected with HIV after having sex with Carl Leone have filed a civil suit, alleging more should have been done to protect his victims.

Bill Sasso represents the four women and said this type of ruling is typical in the judicial system pertaining to sensitive matters.

Sasso expects a decision to be rendered on whether the case will proceed to trial in about a month.

Both organizations are trying to get a court case against them dropped.

Sasso said officials knew Leone was infected.

"With that information, they did effectively nothing to protect the people who had advised them of their relationship with Carl, or of course, those people who would follow who had relationships with Carl," said Sasso.

Lawyers for police and the health unit tell CBC News they met their duties in protecting the public, but have no private legal duties towards the women.

If the suit isn't dropped, a trial will proceed in March.

"It's a very important question as to whether the police and the health unit owe a duty to people who are identifiable victims like we believe that the victims of Carl Leone's conduct were," said Sasso.

Leone was convicted of 15 counts of aggravated sexual assault on April 5, 2008 for knowingly exposing women to HIV.

He was sentenced to 18 years in prison.
