Cheyenne Mayor Rick Kaysen says, despite what many people believe, there is no link between the city's Unified Development Code and a United Nations Document dating back to the early 1990's known as Agenda 21.

Kaysen says the UDC--which officially took effect April 30th--is simply an effort to update and streamline the guidelines for development in the city. Kaysen says Agenda 21--which he describes as a ''nonbinding, philosophical document" has never been approved or even considered by the Cheyenne City Council.

Agenda 21 was originally labeled as a blueprint for sustainable communities. Some critics maintain the document is part of a plan to undermine capitalism and personal freedom and perhaps even pave the way for a world-wide government.
