1. Introduction

See the debian.ch bylaws, in english

2. The organization should share Debian's general visions

The organization's bylaws, activities and political stance should not conflict with the Debian Social Contract.

From the debian.ch bylaws, article 2:

Note that these bylaws were written under the earlier running state of debian.ch actually being a TO. These highlight that the intent behind the debian.ch association foundation was to explicitly be a representative of the Debian project and support it and its activities.

3. The organization should remain loyal to Debian

The organization should be considered fully trustworthy, or provide
guarantees that Debian's assets will be managed according to the Debian
Project's decisions.

From the debian.ch bylaws, article 5, about membership:

4. The organization should provide accountability on assets held in trust

The yearly financial statements are made public after each AGM. Debian Auditors can ask for detailed account statements on request and we're discussing ways of better integration with them.

5. The organization should be reliable, sustainable, and reactive

As for reliability and sustainability, debian.ch has been running since at least 2008 without interruption, with annual general meetings (AGMs) and other in-person meetings.

Between 2011 and 2013, DebConf13.ch in Vaumarcus, was launched and conducted successfully by several debian.ch members. This involvement has hurt these members' reactiveness post-DebConf13 (which is visible through the time it took to fill this procedure); this is getting better these days.
