CARACAS, Venezuela -

Venezuela's opposition says it plans to ask the Supreme Court to rule on whether the constitution allows a delay in the swearing-in of cancer-stricken President Hugo Chavez.

Wednesday's announcement by opposition leader Ramon Guillermo Aveledo comes after Congress voted to postpone Chavez's inauguration, which had been scheduled for Thursday.

Aveledo didn't say when or how the opposition intends to bring its challenge.

Supreme Court President Luisa Estella Morales is scheduled to hold a news conference on Wednesday and may address what role the court could take in the dispute.
