There is no need for elders to record the meeting since there are 3 of them to corroborate what took place while the accused is always alone...Judicial committees are spiritual executions to silence any dissidence from the organization with no consideration for justice.
These men's first goal is not to answer any questions. All they want to do is establish where Isaac stands in regards to the organization. In fact when Isaac attempts to bring proof to his alegations using WT quotes they tell him they don't have all night. The recording shows that these "qualified" spiritual men cannot and do not want to bring back to reason the accused. They only need an excuse to isolate him from the flock to mitigate the danger of being exposed.
