The day a law or an amendment starts to apply. It is often months or years after promulgation, so that people have time to prepare. The Ministry of Justice's English usually says a law "comes into force" or "comes into effect", and sometimes calls the day its "enforcement date". Its "enforcement" more often means the word's other sense, carrying a law out, as in an Order for Enforcement (施行令), the Cabinet Order (政令) that sets out the details for carrying out an Act.
Rules made by the Cabinet to carry out the Constitution and Acts. A Cabinet Order cannot impose duties, restrict rights or set penalties unless an Act delegates that to it.
The Ministry of Justice's English of this passage has a slip, so the English shown is this site's correction of it. The Ministry printed:
Notwithstanding the provisions of the preceding paragraph, the Tokyo District Court, with regard to the action and case preceding paragraph, may make a ruling by the panel of five judges who are to conduct a proceeding and make a judicial decision.
