I duuno if it can be called a 'debate' but there is a lively back and forth, quoting of primary and secondary texts and cross questioning of domain experts (!), appeals to the judges to intervene etc. during what are called 'Fiqhi Seminars' that take place annually here in India. So far as I know, most of the times a consensus is reached during the same seminar but sometimes the matter is deferred until next year. I cannot guarantee that there are no temporary hard feelings but generally the seminars end quite amicably with a public event during which the questions discussed (debated?) and the answers that were agreed upon are made known. The fact that the participants (senior ones at-least) discuss the issues passionately and with a sense of responsibility will be evident to anyone who witnesses the event or listens to the recordings (all the sessions are always recorded) which is natural since many of them spend a great deal of time and energy (I have heard that Mufti Nizamuddin sahib spends a greater part of six months in preparation for every seminar) in doing ground work and gathering opinions from experts in the respective fields that bear on the topics to be discussed in order to themselves reach some definite conclusion or to zero-in on the points that are worth discussing before having to defend their point of views in front of the gathering of scholars. I believe that these should be broadcast live via the internet or at-least the recordings should be made public which, by the way, is not disallowed although few are interested in knowing who-said-what. Yet, I think that the two disadvantages of live broadcasts would be: a. Some of the participants might become self-conscious and not put forth their points of view as boldly as they might do in a private event whereas some would fall prey to ostentation and kibr and other things that sidi mentioned above. b. This is as funny as it is true and inevitable: "Abe*, dekha wo maulana log kaisa jhagda karte hai? Hum ko bolte hai aapas me milke raho aur khud ka haal dekho.... Sub aise hi hai..... Aur unko dekha? Kuchh bol hi nahi rahe the.......isiliye to hamaari qaum itni peechhe hai". *excuse that word but it is a favorite sentence starter on the streets, especially with those folks who think nothing about 'gracing' their gatherings with such mindlessly critical remarks in regards to the ulema as above. wassalaam.
