amparo: amparo

I have blogged before about the term tutela, which is the Colombian version of what is more often
throughout Latin America called amparo.  I have been rendering tutela as writ for protection of constitutional rights, but I was surprised to see that the author chose to keep the term in Spanish in the book

Constitutional Protection of Human Rights in Latin America: A Comparative Study of Amparo Proceedings

I suppose the logic is that 'amparo' proceedings as such don't exist in the US, UK, or Canada.  Ojo, amparo cases generally don't establish precedent.
