The Ninth Amendment of the Bill of Rights was put into the United States Constitution on September 5, 1789 and was voted for by 9 out of 12 states on December 15, 1791.
An NHL referee makes anywhere between $110000 and $255000 a year. A linesman on the other hand makes $72000 up to $162000 a year. Hope this helped.
I know that college basketball referees (D-1 men's NCAA games) make over $2,000 per game and work about 70 games per season. Therefore, the NBA referees will start at closer to $200,000 per year.
