PORTLAND, Ore. -- A two-day hearing in the Horman divorce case was abruptly canceled Wednesday morning. Judge Henry Kantor's office confirmed the hearing was postponed indefinitely.

Terri Horman's lawyer requested the delay, so they can prepare arguments regarding the court's ruling on the testimony of Rudy Sanchez.

On Monday, Judge Kantor ruled that Sanchez may not be cross-examined during the hearing. Sanchez is the landscaper who Terri Horman allegedly tried to hire to kill her husband Kaine.

Terri Horman's lawyers argue the inability to cross-examine Sanchez presents significant and constitutional issues.

Kaine's son, Kyron Horman, disappeared from Skyline Elementary School on June 4, 2010 when he was 7 years old. Investigators said at the time that Terri was the last person to see him.

Kaine filed for divorce and a restraining order against Terri in late June, 2010.
