Paragraph 6 of Article 29 stated that if a petition was successful a referendum should be held within three years. Since the deadline passed on 5 May 1958 without anything happening the Hesse state government filed a constitutional complaint with the Federal Constitutional Court in October 1958. The complaint was dismissed in July 1961 on the grounds that Article 29 had made the new delimitation of the federal territory an exclusively federal matter. At the same time, the Court reaffirmed the requirement for a territorial revision as a binding order to the relevant constitutional bodies.
What did the Hesse state government due when the May 5, 1958 deadline passed?
filed a constitutional complaint

Li Zicheng then led a coalition of rebel forces numbering 200,000[a] to confront Wu Sangui, the general commanding the Ming garrison at Shanhai Pass. Shanhai Pass is a pivotal pass of the Great Wall, located fifty miles northeast of Beijing, and for years its defenses kept the Manchus from directly raiding the Ming capital. Wu Sangui, caught between a rebel army twice his size and a foreign enemy he had fought for years, decided to cast his lot with the Manchus, with whom he was familiar. Wu Sangui may have been influenced by Li Zicheng's mistreatment of his family and other wealthy and cultured officials; it was said that Li also took Wu's concubine Chen Yuanyuan for himself. Wu and Dorgon allied in the name of avenging the death of the Chongzhen Emperor. Together, the two former enemies met and defeated Li Zicheng's rebel forces in battle on May 27, 1644.
When did the battle take place?
May 27, 1644
