I don't think that's quite what WGS said; she sees a JR as a means of restraint on the power of governments/legislatures (which you could argue is our job), rather than a review of an alleged unreasonable use of powers or of allegedly acting beyond/without them.
As to any growth industry in JRs, perhaps that's fuelled by people who simply dislike the outcome of a decision made, rather than objecting to how it came to be made.
