Infect, bulls and blocks are not "useless" to the society because till the end of their lives they do yield their excreta in form of urine and dung which are extremely useful for biogas and manure and they do supply hide and other accessories on their death. Hence to call them "useless" is totally devoid of reality. If the expenses incurred for their maintenance are not covered fully by the return which they give, it may be said that they are "less useful" from material point of view, but our nation has never looked upon such situations purely from material point of, view because if we have not lost the capacity to express our sense of gratitude for the past services rendered by our public servants (who are given pensions) and our incapacitated old parents, we must learn to treat the cow and her progeny in the same manner because they have been the backbone of our agrarian economy, social structure and cultural norms since ages but outlook in this matter can not be like a petty-shop keeper whose concern is always-to see which side the indicator of his weighing balance turns. Constitutional problems which touch the cultural heritage of the nation should never be put in a weighing machine.

Those who oppose the total ban on the slaughter of the cow and her progeny are conveniently forgetting the provisions of Art. 51A as found in cl. (F) (G) & (H) which provide that it shall be the duty of every citizen of India-

(1) to value and preserve the rich heritage of our composite culture, 
(2) to have compassion for living creatures and,
(3) to develop the scientific temper, humanism and the spirit of inquiry and reform, In view of all that is stated above, the above judgment given by the S.C. in Mohd. hanif and others v/s State of Bihar is required to be reviewed so far as the question of the slaughter of bulls and bullocks e. q. t. progeny of cow, is concerned.

A review of this decision is also required on other grounds. The said decision is based on the facts and statistics which are about half a century old. Since then many important and revealing researches are made in the field of bio-gas energy and importance of organic manure. Researches have shown that chemical fertilizers involve great health -hazards and the original traditional sys- tem of using organic manure supplied by cattle dung is more nutritive and gives better production.

Biogas which can be easily and cheaply produced form the cattle excreta is easily available to poor people in villages and is also cheaper. All these facts were marshaled by M. P. H. C. in Hashmattulah case in which reliance was placed on the statistics supplied by an article written by one Mr. Pannalal, the chairman of Animal Welfare Board of India. The S.C. has, however, refused to take these statistics in to judicial consideration on the ground that these was nothing in record to show on what basis (data) these figures were given. Obviously, the court could not have relied on the disputed figures which could not be verified.

It is therefore necessary, before the S.C. is asked to review its judgment in Mohd. Hanif case, to collect reliable date from material economic point of view, till their lifetime. Such data can be gathered by carrying out the actual experiment of the quantity of urine and dung produced by an ascertained number of bulls and bullocks after they become unfit as draught animals during a particular span of time,. Such experiment should also show how this excreta of urine and dung be put to profitable use and what would be the value thereof as against the fodder required to maintain these animals. Even the intangible value of improved organic manure supplied by dung can be assessed. After collecting such data and the opinions of experts supported by affidavits, if possible, the S.C. should be approached for review.  >>>
