I keep repeating that it is not a good idea to do nothing in response to the school's requests to supplement the documentation regarding the pupil's vaccination status.
Doing nothing is not a good idea because in front of a judge, for fine, We have no concrete evidence to have made conscious choices and weighted. In practice, the judge will be induced to think, or he may legitimately think, have to do with bad parents who do not care about the welfare of their children, and then confirm the fine. In fact we're trying to get across the concept that if you do not vaccinate children in some maaniera do them harm, so you're a good parent.
E’ not true that nothing presentar, bad luck for compulsory schooling there is a fine to pay and the student will not be expelled, however it is good to know that it is also possible to request not to pay the fine at all, because there is the right not to be vaccinated, State Law.
I still suggest you to send a letter to the school which reaffirms the right not to immunize given by the Oviedo Convention.
So, before the judge, you can assert your position, and request not to pay the fine being a good parent who deals responsabilemnte of the important problems of the children and assessed knowledge and belief the vaccination issue.
