This article is a discussion of this topic seeking answer to these quastions; First : is proof of punishment for 'Motajarry' stopped on proof of object indecency and subject indecency? Secondly: what is the legal nature of impossible crime? Thirdly: is 'Tajarry' criminalization justified? The approach is that; there is no doubt in 'Tajarry' subjective indecency. And suppossing proof of 'Tajarry' objective indecency proof of punishment is difficult. So 'Tajarry' criminalization as a rule based on religious ethics is not justified.
