One cannot perform of procure a paternity test. Only a judge can order it. This is exactly what I said.

So the judge can simply say no and the (legal) father is now on the hook. And furthermore, the legal system will manufacture a criminal if the legal father decides to test his own DNA with the one of his alleged (for whom he is financially responsible) child.

What if a third party performs the test?

Doesn't matter, even outside of France, the results won't be able to be used. Worse, the person who got the test can get fined or even jailed for it.

I’m curious how a law seeking to prohibit anyone from attempting to prove their own innocence could even be taken seriously by any judge or lawyer with a successful education from a legitimate formal legal institution.

Preventing someone from attempting to prove their own innocence is similar to the witch trials of old and a grotesque violation of human rights. Any sovereign legal system preventing defending ones innocence through modern forensic means, has little grounds to protest if as a result their legal system is openly mocked and ignored by other countries that do support defending self innocence.

The fact that a supposed modern nation with elected officials elections should have a miscarriage of justice this grotesque seems akin to a theocracy or monarchy that decides at arbitrary the outcomes of legal proceedings without any actual consistent basis for ensuring justice is upheld.

Did anything remotely ever happened?

Is suspicion that your child is not yours a "lawful context"?

No, because the law has a sucker and doesn't want you to get out of paying.

How are people not protesting this? Who would even enact such a law?

The government once they found that they would have to pay a very large sum to take care of every child out there whose legal father decided to no longer pay once he found out the child is not his (and/or just to spare the child from all the drama, once the court says yes you're not the biological father but you're still on the hook).

I think it was after a survey on cheating and promiscuity, but I'm not sure of this since this was just something I heard of from other people and I can't find much from a quick search on the internet.

The reasoning is that the priorities of the child come before the priorities of the father, so in order to protect the stability of the family you are not allowed to know.

As to who supports this, a lot of women seems to be in support of it (they have nothing to gain from opposing it) and all the people who seem to 'think of the children'.

Some politicians claim to be against allowing the paternity test on the ground that it is against the values of the republic since it's an aknowlegment of the importance of relations blood, genetics, and race(ism), but these are the words of politicians so they don't mean much.

Is there an alternative that keeps the government from having to pay so much for non paying fathers? Ergo, paternity insurance scheme?
