Although Mr Leal was a Mexican citizen, the Texas authorities failed to notify him of his right to contact a Mexican consulate at the time of his arrest, as required by the Vienna Convention on Consular Relations.
Kuigi Humberto Leal oli Mehhiko kodanik, ei teatanud Texase ametivõimud talle vahistamisel, et tal on õigus võtta ühendust Mehhiko konsulaadiga, nagu on ette nähtud konsulaarsuhete Viini konventsioonis.
