On 18 May 1990, Kohl signed an economic and social union treaty with East Germany. This treaty stipulated that when reunification took place, it would be under the quicker provisions of Article 23 of the Basic Law. That article stated that any new states could adhere to the Basic Law by a simple majority vote. The alternative would have been the more protracted route of drafting a completely new constitution for the newly reunified country, as provided by Article 146 of the Basic Law. However, the Article 146 process would have opened up contentious issues in West Germany. Even without this to consider, by this time East Germany was in a state of utter collapse. In contrast, an Article 23 reunification could be completed in as little as six months.
