Here's a plain English summary of this rule:
If someone serves on the Board of Bar Examiners and misses three meetings of the Board in a row, they automatically lose their seat on the Board. This happens no matter what the reason is for missing those meetings. It doesn't matter if the absences were due to illness, work conflicts, or anything else.
Once a member loses their seat this way, the position becomes open. The Oklahoma Supreme Court then picks someone new to fill that empty spot on the Board.
This rule keeps the Board running smoothly by making sure all members show up and take part regularly. Since the Board of Bar Examiners plays a key role in deciding who can become a lawyer in Oklahoma, the state wants people in these positions who can commit the time and attend meetings consistently.
