If you look at Acts 15 carefully it tells us it was more than just the apostles and older men.. v4 they were received by the congregation.. v12 the entire multitude became silent..v22 the apostles and the older men together with the whole congregation..
the problem that had arisen was in Antioch, Syria where Paul had his base as missionary. The Christian Jews there were expecting Gentile Jews to be circumcised, which was why ALL the brothers wanted to get together to sort it out. Of course not all the brothers in Antioch could go so Paul and Silas were sent out as representatives. The answer given was so that 'we add no further burden to you except these (4) necessary things'.
How many times did Paul get direction from Jerusalem? Take a look at Galatians 1:17-20; 2:1...straight after his conversion to christianity he didn't go to Jerusalem at all! It was 3 years before he visited staying with Peter for just 15 days, during that time he only saw James.. none of the other apostles! After that it was another 14 years till he visited again!
He was directed by the Holy Spirit, not by a governing body (this word does not occur in the scriptures, also if you notice the wording in the publications, in the 1stC it is called 'governing body' in modern times it is called 'Governing Body')...Acts 16:9.10.
