A court in El Salvador has agreed to consider a civil case against former President Mauricio Funes, his wife and one of his sons for possible illicit enrichment.

The San Salvador court press office said Saturday that several government institutions have been ordered to hand over information related to the family's finances, properties and businesses.

Under scrutiny is some $728,000 in unexplained income and expenditures. Funes has 20 days to respond to present evidence in his defense.

The former president has criticized the allegations in the past. He said some of the Supreme Court justices who voted to order the lower court to open the case in February had previously attacked his government while sitting on the Constitutional Court.
