===Who has ultimate authority?===
On the issues like religion, abortion, euthanasia or same-sex marriges,etc. the Constitution of Poland is the supreme act of law in Poland.
At some point, everybody breaks a treaty. You can not order a person or society to commit suicide. They, like Honduras, will just have to face whatever sanctions are prompted by breaking it. But at some point, you stop listening to crazy people and tell them NO. Remember, these people are one-worlders who believe in Agenda 21. They want to reduce world population by 85%.
