1992 Liechtenstein constitutional crisis

[2] On 6 December 1992 a referendum was to be held in Switzerland on a federal resolution on the accession to the European Economic Area (EEA).

[4] Hans-Adam II had previously publicly declared his desires to increase Liechtenstein's independence in foreign policy from Switzerland.

[5] When planning on the date for the Liechtenstein referendum regarding accession to the EEA, Prince Hans-Adam II called for it to be held in advance of the corresponding one in Switzerland, against the wishes of both the government and the Landtag.

[6] In response, notable politicians in Liechtenstein, including former prime minister Gerard Batliner formed the Nonpartisan Committee for Monarchy and Democracy and called for a demonstration against Hans-Adam's threatened dissolution of the Landtag.

As a result, the 1924 customs union treaty was now compromised, and was no longer viable due to conflicting interests regarding accession to the EEA.
