Questão jurídica principal
Whether the amended municipal fee regulation could be applied to the connection fees for the last building of the development.
Decisão extraída
The applicable fee basis was the regulation in force at the time of the connection; the amended rules applied because the relevant connection occurred only after their valid entry into force.
Fundamentação extraída
A municipal fee becomes due when the connection is made and use becomes possible; if the connection is created earlier, the obligation arises only upon later completion of the building. The alleged earlier pipe works did not amount to a usable connection.
