After much debate had taken place, Peter got up and said to them, My brothers, you are well aware that from early days God made his choice among you that through my mouth the Gentiles would hear the word of the gospel and believe. And God, who knows the heart, bore witness by granting them the holy Spirit just as he did us. He made no distinction between us and them, for by faith he purified their hearts. Why, then, are you now putting God to the test by placing on the shoulders of the disciples a yoke that neither our ancestors nor we have been able to bear? On the contrary, we believe that we are saved through the grace of the Lord Jesus, in the same way as they. (Acts 15:7-11)Yes, it was James' judgment but he was only affirming what Peter had already said. James was stating that his judgment agreed with that of Peter; he was not introducing a new or contrary judgment. Additionally, the letter was issued in the name of all the apostles and presbyters, not just as the judgment of James.
Use more analysis when reading!
Peter and Paul were appealing to their fellow apostles, peers, not masters, nor underlings, to protect the sheep they had evangelized from the false influence of the Pharisees, who also sought to influence them to keep the false laws contained in their Takanot and Ma’asim. The same “commandments of men” that Yeshua spent most of his life denouncing and demolishing.
You are trying to create a hierarchy among the believers that Yeshua denounced in no uncertain terms. Read Matthew 23 for understanding, not the catechism.

Yeah, that's why James said "My judgement is"
