Hard to tell.
The record size ozone hole did NOT occur this year, but two or three years ago. This may or may not have had anything to do with "laws" and people following them.
Scientists believe that the actual largest depletion to this layer occurred in 1858 during a very highly active solar flare period. The largest recorded did happen in September of 2006. Recording of the size of this thinning area started around 1986. The concept was proposed as early as 1974 that man could have an affect on the ozone layer. This is a very natural event that everyone agrees is due mainly to a lack of sunlight hitting the ozone layer in a given area. That is why we see no net change in ozone levels near the equator (+/- 25 degrees). The track of information is far too short to even state with a high degree of certainty that man contributes anything to the layer's depletion. We do know that this is a natural event. Man's contributions are still not well understood.
