We see in Acts 15 James presiding over the council in Jerusalem to answer the question about circumcision.
The timeline is this:
1. But some of the sect of the Pharisees who believed rose up, saying, “It is necessary to circumcise them, and to command them to keep the law of Moses.” (Acts 15:5)
2. Jerusalem council convened to discuss the matter. This council was made up of apostles and elders. (Acts 15:6)
3. There was much dispute, then Peter rose up and gave account of the Spirit being given to the Gentiles. (Acts 15:7-11)
4. The apostles, Barnabas and Paul, testify of miracles and wonders performed among the Gentiles. (Acts 15:12)
5. The council becomes silent.
So, the order of the council follows a pattern of opening > question to be considered > testimony of witnesses > consideration of the matter and much discussion.
Then, James begins speaking in verse 13 "And after they had become silent, James answered, saying, “Men and brethren, listen to me..."
Notice that he does so only after Barnabas and Paul complete their account. At this point, the matter is completely presented, discussed, and laid out. Now, it is time for the answer for the question.
James summarizes Peter's account and shows how his decree aligns with the testimony of the witnesses and the prophets in the scriptures.
And then James says something important that gets to the heart of your question "Therefore I judge..." This is the evidence that James presided over the council of apostles and elders in Jerusalem. He gets the last say. If you will, this is like a magistrate, after hearing all the evidence in a case from witness and from various accounts, judging the matter.
It then pleases the council to send certain chosen men to Antioch with a letter created by "The apostles, the elders, and the brethren,..." So after James' judgment, the council discusses how they should proceed. The decide to write a letter and send it with men to the saints in Antioch. After a judgment of a matter there is the resolution of a matter. Judgement is simply declaring what is true. Resolution is the action stage of a council: where things are done.
This was all done in order.
