The ruling was handed down in a personal injury claim between two native speakers of Áncash Quechua, estimated to have around a million speakers in northern Peru.

Magistrate Oswaldo Ener Granados Guerrero enlisted the help of a local cultural directorate to translate his judgment, the BBC reports.

It follows another major milestone, the first sentence handed down in a Quechuan language, which Dr Granados Guerrero achieved last year.

The magistrate has committed to extending Quecha language services to increase inclusion and access to justice.
