Good question.... Once the jury has 'convicted' the accused, now they will proceed to 'sentence' him/her with a punishment. Conviction: it means that one's guilt has been proved in the court. The jury is now convinced that this person is/was the real perpetrator of the crime. Hence they have 'convicted' him in this case. Sentence: Once the accused is 'convicted' through judicial proceedings in the court, now the jury will pronounce the verdict or his 'sentence' (punishment). It can be ... "sentenced to 5 years of rigorous imprisonment" or "sentenced to life imprisonment" or even "sentenced to death" ..... depending on the seriousness of the crime. The court even takes time to decide on the 'sentence'... may be a week or even a month, after the accused has been 'convicted' in the court.

if one person/party has any legal problem with another person/party, the former can "sue" the latter .... which literally means "to file a case" against the opposition. points to remember: We can 'sue' a person. or We can 'file a case' against him in the court. both of these expressions refer the same action.... However 'Suing' or 'filing a case' doesn't necessarily mean that the accused is guilty. He can only be 'convicted' by the jury once his guilt is proved. Only the judge or the jury has the power to 'convict' a criminal. Example: The jury "convicted" Mr. X in the corporate bribery case 'filed' against him in the upper house of the court. Earlier, ABC Company had "sued" Mr. X on charges of bribing its employees to access sensitive business data.
