I am waiting for a precise definition of the term "contributes to the possibility"; without a clear and exact articulation of the mechanism, any conclusion is premature.
How do the research priorities of the Ministry of Justice concretely influence the convening of a government roundtable?
If the link is not formalized by a mandate or an inter-organizational agreement, their influence is at best fortuitous.
For example, if the priorities are published without an official channel connecting the Ministry of Justice to the Legal Services Board, the impact is marginal.
