Following in Mexico’s footsteps last week, the Supreme Court of Argentina has unanimously ruled today on decriminalizing the possession of drugs for personal consumption.

For those who might be concerned with the idea of an “activist judiciary,” the Court’s decision was based on a case brought by a 19 year-old who was arrested in the street for possession of two grams of marijuana. He was convicted and sentenced to a month and a half in prison, but challenged the constitutionality of the drug law based on Article 19 of the Argentine Constitution:

The private actions of men which in no way offend public order or morality, nor injure a third party, are only reserved to God and are exempted from the authority of judges. No inhabitant of the Nation shall be obliged to perform what the law does not demand nor deprived of what it does not prohibit.

Today, the Supreme Court ruled that personal drug consumption is covered by that privacy clause stipulated in Article 19 of the Constitution since it doesn’t affect third parties. Questions still remain, though, on the extent of the ruling. However, the government of President Cristina Fernández has fully endorsed the Court’s decision and has vowed to promptly submit a bill to Congress that would define the details of the decriminalization policies.

According to some reports, Brazil and Ecuador are considering similar steps. They would be wise to follow suit.
