Lone Star Planet by H. Beam Piper

I looked around.

We were on a high balcony, at the end of a long, narrow room. In front of us, windows rose to the ceiling, and it was evident that the floor of the room was about twenty feet below ground level. Outside, I could see the barbecue still going on, but not a murmur of noise penetrated to us. What seemed to be the judge's bench was against the outside wall, under the tall windows. To the right of it was a railed stand with a chair in it, and in front, arranged in U-shape, were three tables at which a number of men were hastily conferring. There were nine judges in a row on the bench, all in black gowns. The spectators' seats below were filled with people, and there were quite a few up here on the balcony.
