"A suspended sentence is a sentence rendered by a judge which will not enforced if the defendant meets certain conditions, such as, among others, performing community service, paying restitution to the victim, completing a drug or alcohol abuse treatment program, or staying out of trouble. If the defendant fails to meet the conditions, the sentence will be enforced. State laws on suspended sentencing vary, but a suspended sentence may count as a conviction for enhancing penalties of future offenses." From http://definitions.uslegal.com/s/suspended-sentence/
I entered a guilty plea for a parking offense, explaining to the judge that I had requested an appearance for trial based on a faulty misunderstanding of the charge (in other words, my defense would have been invalid). The judge must have been feeling good that morning, because he accepted my plea but suspended the sentence (i.e., the fine I would normally have had to pay) and let me walk out scot-free. But, keep in mind that should I land back in court for similar offenses, the prosecutor could bring this up, and at that time a judge might not be so lenient and re-impose the original sentence, along with whatever else might be happening in the new case. So "suspended" is good (for me), but it doesn't mean "dismissed." (That's what that last sentence in the quote is saying.) Probably in Portuguese "arquivado" has a parallel meaning?
