Bad that some who are guilty might go free.
Without a doubt they will - but case mentioned in the article is on weak grounds - a 38 year old sleeping with a 12 year old is clearly wrong, so hopefully the appeal will be thrown out.
Which is why I am in favor of laws being written and passed as slowly as possible. We have to have time to look at and consider all angles.
As you said the grounds for this guys appeal is weak.
