Not every schoolar can make Fatwa
This might help
There are some muftis on some satellite channels who answer all questions without exception. Some people in some gatherings, when a question is posed, rush to answer it and each of them wants to speak before the other. What is the Islamic ruling on this?

Praise be to Allaah.
Ibn al-Qayyim said:

The salaf, the Sahaabah and Taabi’een, used to regard it as makrooh to rush to issue fatwas. Each of them would wish that someone else would take care of it, but if he realized that he had no alternative but to answer, he would do his utmost to find the ruling from the Qur’aan and Sunnah or the words of the Rightly-Guided khaleefahs, then he would give his fatwa. ‘Abd-Allaah ibn al-Mubaarak said: Sufyaan told us from ‘Ataa’ ibn al-Saa’ib from ‘Abd al-Rahmaan ibn Abi Layla who said: I met one hundred and twenty of the Companions of the Messenger of Allaah (peace and blessings of Allaah be upon him) – and I think he said, in the mosque – and there was none of them who had to speak but he wished that his brother would take care of it; there was no one who had to give a fatwa but he wished that his brother would take care of it. Imaam Ahmad said: Jareer told us from ‘Ataa’ ibn al-Saa’ib from ‘Abd al-Rahmaan ibn Abi Layla that he said: I met one hundred and twenty of the Ansaar from among the Companions of the Messenger of Allaah (peace and blessings of Allaah be upon him), and there was no man among them who was asked about something but he would wish that his brother would take care of it, and there was none who had to speak but he would wish that his brother would take care of it.
