South Korea had a strong legal policy when it came to adultery. In just the past six years, more than 5,500 people were formerly charged for cheating on their spouses.
But now it's a cheaters paradise.
Just recently, South Korea's Constitutional Court revoked the 1953 controversial act regarding infidelity, with seven of the nine judges on the panel deeming the law unconstitutional.
"Even if adultery should be condemned as immoral, state power should not intervene in individuals' private lives," said presiding justice Park Han-Chul.
Also, anyone convicted since 2008 will have their case reconsidered.
Under the law, having an affair with a married person was punishable by up to two years in prison.
In recent years, the number of people ending up behind bars for the crime dropped down to a great extent. Data from the state prosecution office says that 216 people were jailed in 2004, though those figure dropped to 42 by 2008. Since then, only 22 have been sent to prison.
"Recently, it was extremely rare for a person to serve a prison term for adultery," said Lim Ji-bong, a law professor at Sogang University in Seoul. "The number of indictments has decreased as charges are frequently dropped."
