Navigation and service



To open pdF-documents you will need a pdf-Reader. You can download the needed program for free on this site:

Not all of the offered downloads provided on this site are barrier-free. Many of the older documents can no longer be edited.

We are doing our best to offer accessible PDF files or to provide the content in HTML format - as long as it is possible and sensible,

You will know if a document is barrier-free by its symbol :

The symbol for old (not barrier-free) documents has one arrows pointing downward.

Barrier-free documents use a symbole showing an arrow pointing downward and an additional plus-symbol.

Should you need non barrier-free documents in any other format please let us know via contact. We will do our best to provide the information in other formats - as long as possible.


The site is structured by a navigationbar on top and a navigation on subsequent topics on the lefthandside.

Additionally you can use the sitemap to get an overview.


You can change the font size via your browser.
Internet Explorer: menu "view" > fontsize
Firefox: menu "view" > fontsize


We offe two kinds of searchfunctions:
A simple search and an advanced search.

The simple search is in the upper right area underneath the navigationbar. Within the "search" you can directly enter one or more criteria. The search results are displayed in a new window.

In advanced search you have additional search and sort options:

  • Sorting of results by relevance or by date
  • Restriction of the results by date

You can narrow the search by entering several search terms in the search and adding a (+) between the search terms (AND link).
You can also use the wildcard (*) for a series of letters or (?) for a single letter.
The tilde symbol (~) at the end of an individual word supports fuzzy searches.


The contents of this site are optimized for printing.
With JavaScript enabled, there is is a button "Print Page" at the bottom of the page . When you click on the button, the Print dialog should open in a new window.
With JavaScript disabled the print-funktion is accessible through "menu" > submenu "Print" ( keyboard shortcut Control + <P>).


We have tried to comply this website with the conditions of the Barrier-free Information Technology Ordinance (BITV) as much as possible. Should you still find barriers on our pages, please send us a notice with a description of the problem you have noticed via contact.
