Welcome to the police state.
If I go to the doctor and get driven by my wife, kid, taxi or bus - does the doctor have to inform the dmv?
If I go to the Pub/bar does the bartender call the Garda or Police automatically since you might want to drive later at night, even if you didn’t drive off yourself?
If I have HIV, do I have to wear a armband with blue Star of David… ah, that was done already, by the NAZI’s.
How far do you want to go there?
Not to mention the incredible burden this would impose on doctors who would now need to gain an additional degree in risk management. Can a person who works in a bowling alley be allowed to work if he has fainting spells? What if he falls head first into the shine-o ball-o?
Perhaps you might feel differently had a loved one died on that plane.
Perhaps you’d feel differently because your loved one died when the pilot had an unreported medical condition that he was afraid to go get checked out because he might be grounded.
There’s a reason there are strong doctor-patient confidentiality rules, and that’s because it’s in everyone’s best interest that people go to the doctor. If someone is afraid he’ll lose his job if he goes to the doctor, he might not go, and that doesn’t make anyone safer.
It comes down to this: Nothing is going to prevent someone from making the wrong decision when confronted with the dilemma of realizing they are unfit for the dream job they have, and that continuing with that job might jeopardize the lives of others.
Either the person is capable of making the right decision, or they aren’t.
Recent report suggests that he lied to the doctors who were treating him:
So getting back to the OP, if the doctors understood that he was not working, hard to see a claim for negligence against them.
Aircraft! Damn it, not aircrafts. Stupid journalists.
Many countries have “mandatory reporting” laws that come into play when someone is at serious risk of a causing significant harm, and someone known as a “mandatory reporter” finds out.
The question is whether this is a case like that. According to the link above, it’s not, in Germany.
There are competing goals at stake. In the US we have mandatory reporting laws. That doesn’t mean that every possible threat has to be reported to the authorities by every possible observer.
