>Is any contact that the target decides is unwelcome harassment? If you greet someone and smile, and they interpret your greeting or your smile as sinister, does this law make you a criminal?

I remember that point being a main part of the debate a few months back, how exactly do you draw the limit? It's different for each women, some of them will enjoy a stranger smiling at them, some others will immediately call it harassment.

Also do you need witnesses? A police officier to witness the harassment? Or just the word of the plaintiff?

I'm at work and I can't dive into the legislation right now, but I doubt they managed to precisely define what constitutes harassment. The secretary for gender equality has been... disappointing, to say the least.
