So even if requested by the mother?

Because I was once shocked to learn how easily it is in some countries (like Portugal) for a woman to have the court force a man to submit to a paternity test [0].

I also heard (I guess a few decades ago) the courts would start automatically an investigation on their own when no man would recognise a child at birth.
