The 'pimping laws' are the ones that make it illegal to live off of the profits of prostitution. Basically, if an escort doing her taxes declares her income specifically coming from her work as an escort, she is opening herself up to charges.
The idea of the court ruling is to better secure the safety of the service workers. The purpose behind quashing this portion of the law is that so service workers have more avenues than getting caught in the classic rut of being under the thumb of an abusive controller (pimp). With the ruling they can go to the police to file complaints and charges in relation to their activities without having to expose themselves to charges.
It is also part and parcel with the keeping of a common baudy house, where the penalties can include the confiscation of the service providers property where they work (in most cases their homes).
In reality it's a nasty system that is in play now. It's designed so that there are automatically 3 charges that immediately get laid against the defendant, communicating, keeping a common baudy house, and living off the avails. All 3 have stiff penalties. If a plea bargain is reached the courts still have the other offenses to prosecute with, and they are considered 'serious' by the prosecution. They can say they are tough on crime because they stack the deck in their favour.
Think of it in sports terms. If the average service provider were a baseball player, getting charges laid against them is akin to getting all 3 strikes on 1 swing, and then going back to the dugout so the team manager can kick you in the stomach....
