The decisions and affairs of most societies are indeed made by either the religious leader or the political leaders, there are cases where some decisions that were made by some political leaders would be protested by the populace because it doesn't fit well with the laws and beliefs set up by some religious leaders bringing anarchy, and problems to the society.
They both play important roles in society, but political leaders are more powerful than religious leaders. When citizens resist laws that contradict the teachings of religion leaders, they only submit to it because of how people follow those religious leaders and can do and undo for their purpose. Otherwise, political leaders have the final say in society.
There are instances when a general dress code would be issued by the government to be worn for certain occasions but because it doesn't go in line with some religious beliefs, there is a show of rebellion towards the political leaders just to obey the religious leader.
This is fine, and I completely agree when such situations arise. The way you dress to go somewhere determines how you are addressed. In a culture where morals are valued, such behaviour from a political leader will not be tolerated in the name of civilisation or trend. The leaders must be modest in everything they do since they are the pillar the society are looking up to.
The truth is, that the two sets of leaders play a great role in shaping the society and in times when conflict might arise in the society and the citizenry might not give a listening hear to the political leaders, the religious leaders become the immediate alternate that can calm the citizens down
This can only occur in a country where religious practise is taught and practised. It has to do with their religious beliefs. In a society where all of this is not practised, I don't believe political leaders will have a problem with the masses when a law is made to be observed.
