“7. To invoke this exception four requirements must be satisfied, namely, (I) it was a sudden fight; (ii) there was no premeditation; (iii) the act was done in a heat of passion; and (iv) the assailant had not taken any undue advantage or acted in a cruel manner. The cause of the quarrel is not relevant nor its I relevant who offered the provocation or started the assault. The number of wounds caused during the occurrence is not a decisive factor but what is important is that the occurrence must have been sudden and unpremeditated and the offender must have acted in a fit of anger. Of course, the offender must not have taken any undue advantage or acted in a cruel manner. Where, on a sudden quarrel, a person in the heat of the moment picks up a weapon which is handy and causes injuries, one of which proves fatal, he would be entitled to the benefit of this exception provided he has not acted cruelly.”
