About Quasi-judicial Items Quasi-judicial decisions before council are constrained by very specific criteria. Specifically, unlike other council decisions, direct fiscal impact to the city organization is not an allowable consideration. Development projects are required to pay fees and taxes to cover the costs of city review, approval processes and the development’s impacts on the city’s capital facilities. Review of the project is part of the P&DS team’s standard workplan, and its impacts are incorporated into the annual revenue forecasting as part of the annual budget development.
