"The Supreme People's Court's Provisions on Several Issues Concerning the Trial of Administrative Cases Related to Workers' Compensation."
The Supreme Court's responses, provisions, judicial interpretations, and so on—we know these carry legal force.
However, these are still internal court regulations!
The reason they hold legal force is because the court acknowledges them.
So, now it's clear, right? Why do we often say, "This workers' compensation claim is obviously a sure win, but why does the Human Resources and Social Security Bureau make such bizarre determinations?"
It's precisely because of this reason.
These judicial interpretations and provisions are effective, but where specifically do they take effect? That depends on who issued them.
The reason judicial interpretations hold strong legal force is because the final adjudication power lies with the court.
