1. Where an application to a city for an exemption from wetland replacement requirements is approved by operation of Minn.Stat. § 15.99 (2000) because the city failed to act on the application within the section 15.99 deadline, the scope of the approval cannot be broader than the city\'s substantive authority to approve such applications.

2. Granting a writ of mandamus that compels a city to approve a request by operation of section 15.99 that the city lacks the authority to approve is an error of law.
