New Hampshire's Senate has voted unanimously to reject changes to the state's anti-bullying law, such as limiting school responsibility in dealing with off-campus incidents.

Senators said Wednesday that the current law is only months old and needs further study before any changes are made.

The current law was amended last year for the electronic age. It defines bullying and cyberbullying and allows schools to step in if the conduct happens outside of school and interferes with a student's education or substantially disrupts school operations.

Many states have been moving in this direction, but some New Hampshire lawmakers wanted to restrict the boundaries to school grounds.

The House passed a bill in March that would remove that provision and make other changes. The Senate's rejection leaves the measure's future in doubt.
