The Transcaucasian Commissariat was established at Tbilisi on 11 November 1917, as the first government of the independent Transcaucasia following the October Revolution in Petrograd.
 The Commissariat decided to strengthen the Georgian–Armenian–Azerbaijani union by convoking a Diet or general assembly ("Sejm") in January 1918.
The Trebizond Peace Conference was a conference held between March and April 1918 in Trebizond between the Ottoman Empire and a delegation of the Transcaucasian Diet (Transcaucasian Sejm) and government.
 The opening session was on 14 March 1918.
 The representatives were Rear-Admiral Rauf Bey for the Ottoman Empire, and Akaki Chkhenkeli, A. Pepinov (as an advisor) as the Transcaucasian delegation.

 After the adoption of labour legislation in 1951, al-Nayhoum set up a Port Workers Union the following year.
 During 1952-1953 five more unions were formed in Cyrenaica.
 Together the six unions formed the General Assembly of Cyrenaican Labor Unions.
 The General Assembly of Cyrenaican Labor Unions had around 3,000 members.

The Diet of the Kingdom of Galicia and Lodomeria, and of the Grand Duchy of Cracow was the regional assembly of the Kingdom of Galicia and Lodomeria, a crown land of the Austrian Empire, and later Austria-Hungary.
 In the history of the Polish parliaments, it is considered the successor of the former "sejm walny", or general sejm of the Kingdom of Poland and the Polish-Lithuanian Commonwealth, and also of the "sejmik", or local councils, in the territories of the Austrian Partition.
 It existed from 1861 until the dissolution of Austria-Hungary in 1918.

Filioque (] ) is a Latin term added to the original Niceno-Constantinopolitan Creed (commonly known as the Nicene Creed), and which has been the subject of great controversy between Eastern and Western Christianity.
 The Latin term "Filioque" describes the double procession of the Holy Spirit in Christianity and is translated into the English clause "and [from] the Son" in that creed:
In politics, a diet is a formal deliberative assembly.
 The term is mainly used historically for the Imperial Diet, the general assembly of the Imperial Estates of the Holy Roman Empire, and for the legislative bodies of certain countries.
 Modern usage mainly relates to the Kokkai of Japan, called "Diet" in English, or the German Bundestag, the Federal Diet.
Jane Marum Roush (born September 24, 1956) is a Virginia lawyer and Judge who served as an interim Justice of the Supreme Court of Virginia.
 On July 27, 2015, Governor Terry McAuliffe announced his appointment of Roush to fill the vacancy created by the retirement of Justice LeRoy F. Millette, Jr. effective July 31, 2015.
 Under the Constitution of Virginia, this original interim appointment was to expire thirty days after the commencement of the next session of the Virginia General Assembly, unless the legislature elected her to a full twelve-year term.
 On August 17, 2015, the General Assembly convened in special session but failed to elect anyone to the full twelve-year term before the Senate of Virginia purported to adjourn sine die.
 The Constitution prohibits one chamber of the legislature from adjourning for more than three days without the consent of the other chamber.
 The Governor claims that this provision applies only to regular sessions of the General Assembly; the House of Delegates and most Senate Republicans claim it applies to special sessions as well, and that the Senate's adjournment was invalid because the House did not consent.
 Because there is legal uncertainty about whether the legislature was still in session, it is unclear whether the governor could fill the vacancy created when Justice Roush's original interim appointment expired on September 16, 2015.
 Nevertheless, the governor announced his view that the legislature was not in session and purported to reappoint her for a second interim term.
 Whether this second interim appointment was valid or invalid has not been determined.
 If valid, the second interim appointment expired on February 12, 2016, thirty days after the regular session of the General Assembly began on January 13, because the legislature did not elect her to a full twelve-year term.
