Question: What country does Lex Gabinia and Pompey have in common?

Context paragraphs:
Pompey: Gnaeus Pompeius Magnus (] ; 29 September 106 BC – 28 September 48 BC), usually known in English as Pompey or Pompey the Great, was a military and political leader of the late Roman Republic.  He came from a wealthy Italian provincial background, and his father had been the first to establish the family among the Roman nobility.  Pompey's immense success as a general while still very young enabled him to advance directly to his first consulship without meeting the normal requirements for office.  His success as a military commander in Sulla's second civil war resulted in Sulla bestowing the nickname "Magnus", "the Great", upon him.  He was consul three times and celebrated three triumphs.

Lex Trebonia: The Lex Trebonia was passed in 55 BC during the second joint consulship of Marcus Licinius Crassus and Gnaeus Pompeius Magnus ("Pompey the Great").  Sponsored by the tribune Trebonius, the legislation granted each outgoing consul an extended five-year proconsular command.  Crassus received the province of Syria, with the barely disguised intention of launching an invasion of Parthia.  Pompeius received the provinces of Nearer Spain and Further Spain, but remained in Rome and conducted his administration through legates.

Lex scripta: Lex scripta pl.  leges scriptae is a Latin expression that means "written or statutory law."  It is in contrast to "lex non scripta", customary or common law.  The term originates from the Roman legal tradition.  Emperor Justinian divides the "lex scripta" into several categories:

Lex Gabinia: Among the laws of ancient Rome, the lex Gabinia (Gabinian Law) was an emergency measure in 67 BC which granted Pompeius Magnus ("Pompey the Great") proconsular powers in any province within 50 miles of the Mediterranean Sea without holding a magistracy.  The law was proposed and passed by the tribune Aulus Gabinius and it was also known as "lex de uno imperatore contra praedones instituendo" or "lex de piratis persequendis".

Lex Manilia: The lex Manilia (Law of Manilius) was a Roman law passed in 66 BC granting Pompey the military command in the East against Mithridates VI of Pontus.

Uniformity policy: The uniformity policy was the concept of implementing Swedish law to the dominions of Sweden during the latter's time as an empire.  It is symbolized by the slogan unus rex, una lex et grex unus ("one king, one law, one people") possibly coined by Johan Skytte, governor-general in Swedish Estonia, Ingria and Livonia.  However, the phrase is also found in the debates on the possible union of Scotland and England in 1607, when Sir Edwyn Sandys noted King James VI & I's view that for a perfect union there should be unus rex, unus grex, una lex.  Most notably, the uniformity policy aimed at abolishing serfdom then common in Estonia, Livonia and the Swedish dominons in the Holy Roman Empire (Ingermanland naturally had a free peasantry).  While implemented in Livonia against the will of the local Baltic German nobles, the Estonian and Pomeranian peasants remained serfs: Estonia had voluntarily submitted to Sweden and thus had been given leeway in keeping the traditional local law code, while Swedish Pomerania had retained its traditional law code when, on behalf of the then ruling Swedish high nobility, the Peace of Westphalia granted it to Sweden while remaining part of the Holy Roman Empire, and not in a formal cession which would have resulted in the implementation of Swedish law.  Swedish law was thus only introduced to Swedish Pomerania after the dissolution of the Holy Roman Empire in 1806.

Lex mercatoria: Lex mercatoria (from the Latin for "merchant law"), often referred to as "the Law Merchant" in English, is the body of commercial law used by merchants throughout Europe during the medieval period.  It evolved similar to English common law as a system of custom and best practice, which was enforced through a system of merchant courts along the main trade routes.  It functioned as the international law of commerce.  It emphasised contractual freedom and alienability of property, while shunning legal technicalities and deciding cases "ex aequo et bono".  A distinct feature was the reliance by merchants on a legal system developed and administered by them.  States or local authorities seldom interfered, and did not interfere a lot in internal domestic trade.  Under "lex mercatoria" trade flourished and states took in large amounts of taxation.

Lex loci celebrationis: Lex loci celebrationis is a Latin term for a legal principle in English common law, roughly translated as "the law of the land ("lex loci") where the marriage was celebrated".  It refers to the validity of the union, independent of the laws of marriage of the countries involved: where the two individuals have legal nationality or citizenship, or where they live (reside or are domiciled).  The assumption under the common law is that such a marriage, when lawfully and validly celebrated under the relevant law of the land, is also lawful and valid.

Lex orandi, lex credendi: Lex orandi, lex credendi (Latin loosely translated as "the law of praying [is] the law of believing") is a motto in Christian tradition, which means that it is prayer which leads to belief, or that it is liturgy which leads to theology.  It refers to the relationship between worship and belief, and is an ancient Christian principle which provided a measure for developing the ancient Christian creeds, the canon of scripture and other doctrinal matters based on the prayer texts of the Church, that is, the Church's liturgy.  In the Early Church, there was liturgical tradition before there was a common creed and before there was an officially sanctioned biblical canon.  These liturgical traditions provided the theological framework for establishing the creeds and canon.

Lex non scripta: Lex non scripta is a Latin expression that means "'law not written'" or "'unwritten law'".  It is a term that embraces all the laws which do not come under the definition of written law or ""lex scripta"" and it is composed, principally, of the "law of nature", the "law of nations", the "common law", and "customs".
