The states parties to the international anti-corruption conventions of the UN, the Council of Europe and the OECD mutually monitor implementation at national level. This puts political pressure on all states parties to comply equally with their obligations.
Like all other states parties, Switzerland participates in the review mechanisms. This means that it undergoes regular reviews by two other states selected at random and, in turn, reviews other states.
There are different rules for the different review mechanisms. What they have in common is that a report, which can also contain recommendations, is published at the end of each review. Switzerland's country reports are available on the websites of the international lead organisations:
UN – UNCAC
Council of Europe - GRECO
OECD
Combating corruption in Switzerland
In Switzerland, the implementation of international treaty obligations, the response to the recommendations, and the overall fight against corruption are cross-cutting tasks involving various federal offices and authorities at all levels. In order to supervise and coordinate this work, the Federal Council set up an Interdepartmental Working Group on Combating Corruption on 19 December 2008. The FDFA chairs and acts as the secretariat of the Interdepartmental Working Group on Combating Corruption.
FDFA: Interdepartmental Working Group on Combating Corruption
On 25 November 2020 the Federal Council approved its anti-corruption strategy for the 2021–24 period. This strategy defines numerous objectives ranging from prevention and law enforcement to international cooperation. It addresses direct measures at the Federal Administration which will be responsible for their implementation. The Interdepartmental Working Group (IDWG) on Combating Corruption is responsible for monitoring and promotes implementation of the measures by organising exchanges of information on the progress made and encouraging interaction between the relevant federal offices.
