The existence of a quota and rotational rule by itself will not violate article 14 or article 16 of the Constitution." For all the reasons stated above we find that there is nothing wrong in the respondent 1 Corporation proceeding to appoint Assistant Engineers (Civil) by direct recruitment as per the Recruitment Regulations or in fixing the 50:50 quota and working it out or in the selection of the petitioners in Writ petition 1194 of 1979 as Assistant Engineers pursuant to the decisions to appoint 8 Assistant Engineers (Civil) by direct recruitment in the interviews held for that purpose on 6th and 7th March, 1979 and that respondent 1 and 2 should issue orders of appointment to those posts to 8 of the petitioners in Writ petition 1194 of 1979 who are in the select list within six weeks from this date if not already issued as undertaken by Mr. U.R. Lalit on 29.7.1981 within five months from that date.
