Let's reduce this to inputs and constraints: the mere existence of research priorities from the Ministry of Justice is not a sufficient condition for the proposed roundtable by the Legal Services Board (LSB).
The causal mechanism is weak because the MoJ's priorities are only declarative inputs, without a mechanical obligation for the LSB to comply.
The holding of the roundtable depends much more on the LSB's operational constraints, such as funding or human resources, which are not influenced by research directives.
For example, if the LSB lacks budget or staff, the MoJ's priorities will not compensate for these concrete obstacles to organizing the event.
