The executive can enforce judicial orders. This is civics 101.

The ban is an ex post facto law. Rights holders to property have a legitimate reason to defend those rights across policy changes.

An ordinance banning ALPRs that impacts previously-installed Flock cameras is not an ex post facto law.

Generally, the ballgame here is over publicly-owned cameras, so none of this is really apposite.
