I can comment on some of this. The new process that the government put in place recently does a lot to remedy some of the gaps. The government called upon people to apply if they wished to become committee members on the judicial advisory committees. There's much more diversity now on these committees. The questionnaires are also longer and call for more information to be provided to committee members. It's a more transparent approach that has done a lot to increase diversity in the selection of eligible candidates. That will go some way in addressing some of these issues, but not all.
On April 11th, 2017. See this statement in context.
