Polo Rules

I was under the impression that the game restarted when 2 players from the scoring team had gone over the halfway line.
At least this is what I was told after conceding a goal when I thought the game wasn't restarted as all 3 of us were not in our own half.

From the league site:

5 – After a goal is scored:
5.1 – The scoring team returns to their half of the court.
5.2 – The conceding team gets possession of the ball and stays in their half of the court.
5.3 – Play will not resume until all 3 players on the scoring team have returned to their own half

From the tournament rules we were playing at the weekend:

5.2 - After a goal is scored, or a game "reset"
5.2.1 - The referee will stop the time.
5.2.2 - Both teams return to their half of the court.
5.2.3 - The team that was scored upon retains possession of the
ball.
5.2.4 - The defending team must wait for the ball or an
offensive player to cross the halfway line.
5.2.4.1 - Play continues and the time restarts once the
ball or an offensive player cross the halfway line.
5.2.4.2 - The main referee has to the authority to call
“game on” and restart the time.
