Mere existence of motive to commit an offence by itself cannot give rise to an inference of guilt nor can it form the basis for conviction
Needless to say motive is that which impels a person to do a particular act. There can be no action without a motive. Motive may create a very strong suspicion but it cannot take the place of proof.Mere possibility of existence of motive cannot make the accused guilty, as held by the Hon'ble Apex Court in the case of Sarwan Singh Rattan Singh vs. State of Punjab. Where the prosecution case depends on circumstantial evidence, motive assumes significance and goes a long way to prove the case of the prosecution as held by the Hon'ble Apex Court in the case of Shivaji vs. State[Para No.36]
Mere existence of motive by itself is not an incriminating circumstance and it cannot give rise to an inference of guilt nor can it form the basis for conviction. Motive for the crime, even if adequate, cannot by itself sustain a criminal charge. In the case in hand, we have discussed elaborately how the prosecution is found wanting in establishing the "last seen" theory. Therefore, practically, there is no evidence to establish any of the circumstances, which in such type of cases, need to be established by the prosecution and even if we assume for the sake of argument that the accused was harboring a motive to commit the murder of the deceased, that in itself, for want of other positive evidence, will not sail the prosecution through.[Para No.37]
