What does "governed exclusively by the law of the Federal Republic of Germany to the exclusion of the UN Convention on Contracts for the International Sale of Goods" mean? Use simple language pls.
It means that German courts are responsible for deciding any disputes or claims between parties who have entered into a contract involving goods from outside of Germany and which involves international sale, meaning it includes transactions where one party is located in another country. This also applies if there has been no written agreement but both sides expect that they will be bound after delivery. In these cases, German court decisions can still be appealed to an higher court (like the Supreme Court) before being finalized.
