Home Dictionary Name: cast ironCast iron
Cast iron, 'Cast iron' is defined in the Concise Oxford Dictionary as 'a hard alloy of iron, carbon and silicon cast in a mould'. According to New Lexicon Webster's Dictionary of English Language, the word 'cast iron' means 'an iron-carbon alloy produced in a blast furnace. It contains up to 4% carbon, and is more brittle, but more easily fused, than steel'. According to Van Nostrand's scientific Encyclopedia, 'cast iron' is 'primarily the product of remelting and casting pig iron'. (Interestingly, the expression 'cast-iron' - with a hyphen between 'cast' and 'iron' - has been defined separately as meaning 'made of cast iron', Bengal Iron Corpn. v. CTO, 1994 Supp (1) SCC 310: AIR 1993 SC 2414 (2417). [A.P. General Sales Tax Act, (6 of 1957)]Cast iron casting in its basic or rough form just be held to be 'cast iron'.

Scheduled caste
Scheduled caste, article 341 makes it clear that a 'Scheduled Caste' need not be a 'caste' in the conventional sense and, therefore, may not be a caste within the meaning of Article 15(2) or 16(2). Scheduled Castes become such only if the President specifies any castes, races or tribes or parts or groups within castes, races or tribes for the purpose of the Constitution. So, a group or a s. of a group, which need not be a caste and may even be a hotchpotch of many castes or tribes or even races, may still be a Scheduled Caste under Article 341. Likewise, races or tribal communities or parts thereof or part or parts of groups within them may still be Scheduled Tribes (Article 342) for the purpose of the Constitution. Under this definition, one group in a caste may be a Scheduled Caste and another from the same caste may not be. It is the socio-economic backwardness of a social bracket, not mere birth in a caste, that is decisive. Conceptual errors creep in when traditional obsessions ob...
Scheduled castes and scheduled tribes
Scheduled castes and scheduled tribes, it is an accepted fact that members of the Scheduled Castes and Tribes are by the large backward in comparison with other communities in the country. This is the result of historical cause, T. Devadasan v. Union of India, AIR 1964 SC 179: (1964) 4 SCR 680.(ii) Scheduled castes and scheduled tribes are not a caste within the ordinary meaning of caste. Scheduled Castes and tribes are descriptive of backwardness. It is the aim of our Constitution to bring them up from handicapped position to improvement. No Court can come to a finding that any cast or any tribe is a Scheduled Caste or Scheduled tribes. Scheduled Caste is a caste as notified under Article 366(25), State of Kerala v. N.M. Thomas, AIR 1976 SC 490: (1976) 2 SCC 310: (1976) 1 SCR 906.Scheduled Castes and Scheduled Tribes, shall have the meanings respectively assigned to them in the clauses (24) and (25) of Art. 366 of the Constitution of India; Maharashtra State Public Services (Reservati...
Caste
Caste, Since a caste is a social combination of persons governed by its rules and regulations, it may, if its rules and regulations so provide, admit a new member just as it may expel an existing member. The rules and regulations of the caste may not have been formalised: they may not exist in black and white: they may consist only of practices and usages, C.M. Arumugam v. S. Rajgopal, (1976) 1 SCC 863: (1976) 3 SCR 82: AIR 1976 SC 939 (948). [Constitution (Scheduled Castes) Order, 1950]A caste is a horizontal segmental division of society spread over a district or a region or the whole State and also sometimes outside it. Homo Hierarchicus is expected to be the central and substantive element of the caste system which differentiates it from other social systems. The concept of purity and impurity conceptualises the caste system. There are four essential features of the caste system which maintained its homo hierarchicus character: (1) hierarchy; (2) commensality; (3) restrictions on m...
