Operate away from the public eye - judges rarely used to speak out publicly on issues of law or public policy
Still expected to avoid being drawn into open defence of their rulings
Restriction of political activity
Judges are not supposed to campaign on behalf of a political party or pressure group. Judges retain the right to vote, but their political views should not become a matter of public record
High level training
Highly trained profession regulated by the Law Society - experience required means they have demonstrated they are able to put personal bias aside
Legal justifications of judgements
Senior judges are expected to explain how their judgements are rooted in law - makes it less likely they will be guided by personal bias
