Denmark toughened its rape law Thursday by criminalizing sex without explicit consent, a long-awaited victory for assault survivors and human rights groups.

In order to bring a rape charge, the law previously required proof of violence, threat or evidence that the victim was unable to fend off the assault. But the new legislation broadens the definition.

¡°Now it becomes clear that if both parties do not agree to sex, then it is rape,¡± Justice Minister Nick Haekkerup said after lawmakers unanimously approved the measure, which takes effect Jan. 1.
