Summary This article arises with the aim of making a scarcely explored right visible: that of indigenous peoples in Mexico to maintain and develop their own legal systems in accordance with their own co-movision, customs and cultural identity. This is protected by constitutional and conventional cuts to autonomy and self-determination. I would like to point out that it is not my intention to exhaust with the following reflections the breadth and diversity of the present topic, since it would be impossible to carry out this task. My primary objective will therefore be to open up the debate and dialogue on a right which, in my view, I consider essential for indigenous peoples to be able to maintain their way of life.
