This was an antitrust ruling, so chances are that the process was something like:

- app developer (here, the giant state-backed energy company ENEL) complains to antitrust authority about getting denied access to store

- authority asks Google to justify itself

- Google makes a very weak argument, refuses to disclose the internal decision-making process that resulted in blocking access

- authority goes “oh really?”, proceeds to slap Google with a fine

Now Google can decide whether they want to take this to court (which, being Italy, will probably take 5 to 10 years); pay the fine and allow ENEL in; or just ignore the ruling and dare the state to slap them harder (which again, would probably mean a good 5+ years will pass before sanctions are actually enacted, but might result in higher fines).
