Controversial Brazil law curbing Indigenous rights comes into force

Time marker' legislation means Indigenous peoples can only lay claim to lands they occupied in 1988, invalidating scores of claims

A controversial law curtailing Indigenous rights in Brazil has come into force, marking a victory for the powerful agribusiness caucus in congress.

The new legislation upholds the so-called time marker" theory (marco temporal), which establishes that Indigenous peoples can only lay claim to land they physically occupied as of October 1988, when the current constitution was promulgated.
