Yes, of course. Imagine a father who rapes his child and abuses his wife. The child is removed from the father by the mother who goes into hiding, but with temporary legal approval.
We don't want the father (who likely retains some element of parental responsbility until the court case has finished) to be able to get the child's location by SARs.
In Europe children are humans and humans have rights. Children are not the property of their parents.
This seems like a problem with the temporary legal approval and not a genuine response to the question. In the US, parents accused of abuse are denied all parental privilege/responsibility at the beginning of the accusation until it is proven that the parent was innocent.
If your argument is that this regulation is fine as long as all other regulations are infallibly drafted and implemented, that only works until the other regulations are fallibly drafted and implemented. But fallible regulations are the rule rather than the exception.
Battered spouses frequently run away without notifying authorities, because leaving gets them out of the situation whereas contacting authorities extends and inflames the conflict.
And, because everything is a trade off, if you pass a law which is highly protective of victims then the abuser can file a false abuse complaint against the victim, then kidnap the children and deny the victim all access to their children until the fraudulent abuse complaint is dismissed.
Parental alienation is a thing. If the mother was making it up you'd be denying the child's right to a family life with its father, and the father's right to a family life with his child.
I was just stating how it works in the US. My mother was accused by neighbors when I was a child (certainly a much weaker tie than parental). I was taken away by the state immediately while they investigated. The claim was determined to be founded and the state took permanent custody.
As a parent, yes. It's a gradient that starts at "no" when they are an infant to "yes, just like any other adult" when they turn 18. My kids are elementary age and I definitely respect their increasing right to privacy, even from me.
This is the centre of a hot button issue in Alberta, Canada's politics. The previous provincial government passed a bill that prohibited schools and teachers from telling parents that their child had joined a GSA [0]. The new conservative government decided to change that aspect of the legislation and controversy ensued. Many believe that this change would put LGBT children at risk [1][2].
Not sure, if you are raising a child and they are hiding information or data from you that could be detrimental to their development or may imply intent of hurting or maiming others do you have a right to know about it so you can take action?
Could even be nasty in a case where separated parents have 50/50 custody and one parent uses GDPR to get data on what another parent might be doing with their child and build a case against them.
Not per se, no. But there are many overbearing/controlling parents out there. It's easy to imagine scenarios where parental access to GDPR data could be a bad thing (and yet other scenarios where it could be a good thing).
