The DC heroes are accountable... To themselves. (or in this case, to other heroes) they're not really accountable to anyone else. In effect they're a superpowered aristocracy, they're not oppressive dicks (far from it) but there's really no way of making them NOT be oppressive dicks.
DC has done some nose-tweaking of the government wanting to monitor/control meta humans, especially in OUTSIDERS (vol 3.) #50. Batman explains that public superheroes were going to start being monitored by the FBI, CIA, Metahuman Affairs, etc. With the heroes "under the microscope" the bad guys could have more options.
For the most part, the DCU government is more concerned with keeping track of superheroes rather than telling them what and what not to do.
