Criminal Procedure Code, 1973
Section 319—Exercise of power by Court—Joint trial with the other accused—Trial court having regard to the facts and circumstances of a particular case may take a decision as to whether the accused who has been summoned under Section 319 CrPC may be tried conjointly with the existing accused persons or in a given case the trial court may take a decision to try him separately so there is no boundation for the trial court to try all the accused persons together. 
Held : Though Section 319 of CrPC provides that such person summoned as per sub-section (1) thereto could be jointly tried together with the other accused, keeping in view the power available to the Court under Section 223 of CrPC to hold a joint trial, it would also be open to the learned Sessions Judge at the point of considering the application under Section 319 of CrPC and deciding to summon the additional accused, to also take a decision as to whether a joint trial is to be held after summoning such accused by deferring the judgment being passed against the tried accused. If a conclusion is reached that the fresh trial to be conducted against the newly added accused could be separately tried, in such event it would be open for the learned Sessions Judge to order so and proceed to pass the judgment and conclude the trial insofar as the accused against whom it had originally proceeded and thereafter proceed in the case of the newly added accused. However, what is important is that the decision to summon an additional accused either suo-moto by the Court or on an application under Section 319 of CrPC shall in all eventuality be considered and disposed of before the judgment of conviction and sentence is pronounced, as otherwise, the trial would get concluded and the Court will get divested of the power under Section 319 of CrPC. Since a power is available to the Court to decide as to whether a joint trial is required to be held or not, this Court was justified in holding the phrase, “could be tried together with the accused” as contained in Section 319(1) of CrPC, to be directory as held in Shashikant Singh (supra) which in our opinion is the correct view.

Section 319—Summoning of additional accused—Exercise of power by Court—Question as to whether trial court has the power under Section 319 of CrPC for summoning additional accused when the trial with respect to other co-accused has ended and the judgment of conviction rendered on the same date before pronouncing the summoning order—Power under Section 319 of CrPC is to be invoked and exercised before the pronouncement of the order of sentence where there is a judgment of conviction of the accused—In the case of acquittal, the power should be exercised before the order of acquittal is pronounced—Hence, the summoning order has to precede the conclusion of trial by imposition of sentence in the case of conviction—If the order is passed on the same day, it will have to be examined on the facts and circumstances of each case and if such summoning order is passed either after the order of acquittal or imposing sentence in the case of conviction, the same will not be sustainable.

Section 319—Summoning of additional accused—Exercise of power by Court—Question as to whether trial court has the power under Section 319 of the CrPC for summoning additional accused when the trial in respect of certain other absconding accused (whose presence is subsequently secured) is ongoing/pending, having been bifurcated from the main trial—Trial court has the power to summon additional accused when the trial is proceeded in respect of the absconding accused after securing his presence, subject to the evidence recorded in the split up (bifurcated) trial pointing to the involvement of the accused sought to be summoned—But the evidence recorded in the main concluded trial cannot be the basis of the summoning order if such power has not been exercised in the main trial till its conclusion.
[Para 33]
Section 319—Exercise of power—Guidelines to be followed by competent court issued as under :
(i) If the competent court finds evidence or if application under Section 319 of CrPC is filed regarding involvement of any other person in committing the offence based on evidence recorded at any stage in the trial before passing of the order on acquittal or sentence, it shall pause the trial at that stage.
(ii) The Court shall thereupon first decide the need or otherwise to summon the additional accused and pass orders thereon.
(iii) If the decision of the court is to exercise the power under Section 319 of CrPC and summon the accused, such summoning order shall be passed before proceeding further with the trial in the main case.
(iv) If the summoning order of additional accused is passed, depending on the stage at which it is passed, the Court shall also apply its mind to the fact as to whether such summoned accused is to be tried along with the other accused or separately.
(v) If the decision is for joint trial, the fresh trial shall be commenced only after securing the presence of the summoned accused.
(vi) If the decision is that the summoned accused can be tried separately, on such order being made, there will be no impediment for the Court to continue and conclude the trial against the accused who were being proceeded with.
(vii) If the proceeding paused as in (i) above is in a case where the accused who were tried are to be acquitted and the decision is that the summoned accused can be tried afresh separately, there will be no impediment to pass the judgment of acquittal in the main case.
(viii) If the power is not invoked or exercised in the main trial till its conclusion and if there is a split-up (bifurcated) case, the power under Section 319 of CrPC can be invoked or exercised only if there is evidence to that effect, pointing to the involvement of the additional accused to be summoned in the split up (bifurcated) trial.
(ix) If, after arguments are heard and the case is reserved for judgment the occasion arises for the Court to invoke and exercise the power under Section 319 of CrPC, the appropriate course for the court is to set it down for re-hearing.
(x) On setting it down for re-hearing, the above laid down procedure to decide about summoning; holding of joint trial or otherwise shall be decided and proceeded with accordingly.
(xi) Even in such a case, at that stage, if the decision is to summon additional accused and hold a joint trial the trial shall be conducted afresh and de novo proceedings be held.
(xii) If, in that circumstance, the decision is to hold a separate trial in case of the summoned accused as indicated earlier;
(a) The main case may be decided by pronouncing the conviction and sentence and then proceed afresh against summoned accused.
(b) In the case of acquittal the order shall be passed to that effect in the main case and then proceed afresh against summoned accused.
