I know that you can choose to opt out of doing jury duty in the UK if you are a minister of religion.
So brothers and sisters were stating on their application form that they were so they could get out of doing it. Then the WT Branch sent out a letter saying that only congregation elders could use this cop out clause.
So the irony is that on the one hand every witness is told during the baptism talk "today you are qualified as ministers of God" they aren't allowed to say so in any secular setting until they have qualified as an elder.
Elders can choose to use their rights as a Minister of Religion to not be on a jury, BUT it is a conscience matter. The brother who is the coordinator of the congregation I used to be in, was twice on jury duty. He told us about one case which was a murder with his words "but we nailed the bastard!" I reckon you can all guess what he is like on judicial committees as well...
