In cities with a city attorney, the city attorney:

1. (1) may prosecute violations of city ordinances;
2. (2) may prosecute, under state law, infractions and misdemeanors occurring within the boundaries of the municipality;

3. (3) has the same powers in respect to violations as are exercised by a county attorney or district attorney, except that a city attorney's authority to grant immunity shall be limited to:

   1. (a) granting transactional immunity for violations of city ordinances; and
   2. (b) granting transactional immunity under state law for infractions and misdemeanors occurring within the boundaries of the municipality;
4. (4) shall represent the interests of the state or the municipality in the appeal of any matter prosecuted in any trial court by the city attorney;
5. (5) may cooperate with the Office of the Attorney General during investigations; and
6. (6) may designate a city attorney from another municipality or a public prosecutor to prosecute a matter, in the court having jurisdiction over the matter, if the city attorney has a conflict of interest regarding the matter being prosecuted.
