His name is Eduardo Jorge Prats*. Here, Clave Digital makes a good work quoting him on why he considered the Supreme Court of Justice of the Dominican Republic to have abdicated; the quote

What is worse, our Highest Tribunal of justice abdicates on its role of custodian of the Constitution when it legitimates that the Legislative Branch may interpret to its will the Constitution, by defining -capriciously constitutional terminology and concepts

He compared the situation with that of the Legislative Branch proceeding to unduly ground the concept of prior restraint and censorship - a subject matter of freedom of expression, embodied in the Dominican Constitution. [hypothetical]

According to the source, he also expressed concern about how the Supreme Court opinion may expose the Dominican Republic to face international reprehension.
