Presumably there are custodial sentences applicable, what is the minimum and maximum length?
The potential sentences are set forth in the Penal Code of Portugal at Articles 153 to 162. The statute for each offense sets forth a maximum penalty. The most serious offense of this type is punishable by up to 16 years in prison.
There is not always a minimum penalty and sentencing alternatives earlier in the Penal Code undermine the minimum sentences set forth in the selected cases where they are present so that they don't really mean what they appear to mean. So, it is not informative to try to list minimum penalties.
