In relation to head 4(3)(g, which refers to intimidation or harassment, it seems there is a difference between head 4 and head 6 when it comes to harassment. Is it a graduated approach where there is a lower threshold of harassment under head 4 and then what seems to be more persistent harassment under head 6? Is that the difference?
