Rights groups and politicians in Colombia have welcomed a decision by the country’s Constitutional Court, which ruled this week that the government failed to consult local communities over its plan to restart aerial fumigation of coca crops.

In a decision on Wednesday, the court said the government of President Ivan Duque could not at this stage move forward with plans to carry out aerial spraying with herbicide glyphosate. It said Bogota must first adequately consult with communities that could be affected.

Earlier that year, the World Health Organization (WHO) linked glyphosate – marketed under the brand name RoundUp in the US – as a probable human carcinogenic.
