That’s exactly why they’re doing it, and we can use that against them. For instance, by framing their decision not to appeal as an admission, it serves to strengthen the constitutional challenge. In turn, it’s more likely that the provision against purchasing will also be struck down. Why? Since in addition to the obvious argument that it makes things more dangerous for the ladies, the court will find that working together, hiring third parties, advertising etc. is de facto ‘legal’, whereas purchase is not. The sheer contradiction would be enough to have the remaining parts of the law struck down as well, lest a judge try to explain a plausible rationale for keeping it in while maintaining a straight face!
