The ballot laws of the Roman Republic were four laws which introduced the secret ballot to all popular assemblies in the republic. They were all introduced by tribunes, and consisted of the lex Gabinia tabellaria of 139 BC, applying to the election of magistrates; the lex Cassia tabellaria of 137 BC, applying to juries except in cases of treason; the lex Papiria of 131 BC, applying to the passing of laws; and the lex Caelia of 107 BC, which expanded the lex Cassia to include matters of treason. Prior to the ballot laws, voters announced their votes orally to a teller, essentially making every vote public. The ballot laws curtailed the influence of the aristocratic class and expanded the freedom of choice for voters. Elections became more competitive. In short, the secret ballot made bribery more difficult.

A ballot selfie is a type of selfie that is intended to depict the photographer's completed ballot in an election, as a way of showing how the photographer cast their vote. Ballot selfies have risen in prominence alongside the increasing availability of smartphone digital cameras and the use of social media in the 21st century. They have also generated controversy as potential violations of laws enacted in the late 19th and early 20th centuries to curtail vote buying, particularly in the United States, though some U.S. courts have rejected restrictions on ballot selfies as inconsistent with the U.S. Constitution's First Amendment guarantees of freedom of speech.

The Italian electoral law of 2015, also known as Italicum, was an Italian electoral law passed in 2015. The law, which came into force on 1 July 2016, regulated only the election of the Chamber of Deputies, replacing the previous electoral law of 2005, which had been ruled partly unconstitutional by the Constitutional Court of Italy in December 2013. It provided for a two-round system based on party-list proportional representation, including a majority bonus and a 3% election threshold. Candidates would have run in 100 multi-member constituencies using open lists. The largest party which won over 40% of the vote would automatically win a majority of seats; if no party won 40% of seats, a second round of voting would be held between the two largest parties, with the winner of the second round winning a majority of seats. The name "Italicum" was coined in 2014 by Democratic Party secretary and later Prime Minister Matteo Renzi, who was one of the legislation's main proponent.

The Senate and the Chamber of Deputies did not differ in the way they allocated the proportional seats, both using the largest remainder method of allocating seats.
