dont worry my friend,law is a noble proffessional,let me help you as follows;-according to your explaination we must keep ourselves busy in the CRIMINLA PROCEDURE CODE CAP 20 OF THE LAWS OF TANZANIA. PARTICULARLY UNDER SECTION 137 AND SECTION 138,HOWEVER SECTION 137 OF THE SAID LAW PROVIDES AS HEREUNDER ENUMERATED;-
A person who has once been tried by a court of competent jurisdiction for an offence and convicted or acquitted of such offence shall, while such conviction or acquittal has not been reversed or set aside, not be liable to be tried again on the same facts for the same offence. BUT ALSO SECTION 138 OF THA SAME LAW PROVIDES FURTHER THAT;-
A person convicted or acquitted of any offence may be afterwards tried for any other offence with which he might have been charged on the former trial under subsection (1) of section 134. IN ORDER FOR U TO BE CLEAR I ALSO INSERT SECTION 134(1) OF THE SAME LAW SO AS FOR U TO BE CLEAR;-
134. Joinder of two or more accused in one charge or information
(1) The following persons may be joined in one charge or information and may be tried together, namely–
(a) persons accused of the same offence committed in the course of the same transaction;
(b) persons accused of an offence and persons accused of abetting or an attempt to commit such an offence;
(c) persons accused of different offences committed in the course of the same transaction;
(d) persons accused of any offence under Chapter XXV to XXXI of the Penal Code * and persons accused of receiving or retaining property, possession of which is alleged to have been transferred by any such offence committed by the first-named persons, or on abetment of or attempting to commit either of such last-named offences;
(e) persons accused of any offence relating to counterfeit coin under Chapter XXXVI of the Penal Code *, and persons accused of any other offence under the said Chapter relating to the same coin, or of abetment of or attempting to commit any such offence; or
(f) persons accused of any economic offence under the Economic and Organised Crime Control Act *.
(2) For the avoidance of doubt, it is hereby declared that nothing in this section or in this Act shall be construed as preventing persons who have been committed for trial separately from being joined in one charge or information and being tried together if they are persons who fall under any of the categories specified in subsection (1). I HAVE NO DOUBT UP TO THAT AND I THINK YOU ARE NOW CLEAR OF THE PROBLEM FACING YOUR RELATIVE-THANKS
