The broad definition of anti-social behaviour encompasses a wide range of unacceptable behaviour. While it may be well-established and understood by some authorities, its breadth and subjectivity allows for inconsistency in its application and risks sweeping up less serious matters along with behaviour that demands a legal response. This can disproportionately affect vulnerable groups and result in measures being taken that interfere with human rights to an unjustified extent. It is therefore particularly important that measures taken to combat anti-social behaviour contain effective safeguards against their disproportionate use. (Conclusion, Paragraph 26)
