What does "jura novit curia" means in Spanish Law?

The aphorism "jura novit curia" is not only a rule of spanish procedural law, which means that the judge must find ex officio the norm that corresponds to the fact, without waiting for the parties to indicate it.

This important principle of Spanish Law is also a rule of forensic correction, which indicates to the lawyer, if she/he feels interest in the cause she/he defends, that it is convenient for her/him not to give the impression or the tone of teaching the judges the law.

Some times good lawyering requires that judges are considered as teachers. A lawyer should be a great jurist, but also a good psychologist, who, in occassions, when speaking to the judges must try not to anger them with great displays of wisdom.
