Line judges

Allgemeines

A distinction is made between the 2- and 4-line judge system. The positions of the line judges are named 1 to 4 counterclockwise, starting at the first referee. While in the 4-line-judge-system all positions are taken, in the 2-line-judge-system only positions 1 and 3, but here named 1 and 2, are taken.
