This mechanism is positioned between monarchy and democracy. There are ample factory of permanence and control available in it. Every mechanism of governance, regardless of what form it has, has some fraction of aristocracy in it. In this type of administration, laws are found to be all-pervading.

Negative aspect of Aristocracy: 

The most negative aspect of aristocracy is that it is not necessary the every person born in high family or in aristocratic class has the capability to administer well. Human society is not proficient in the art of choosing the best. Hence, in practical terms, aristocracy becomes the administration of the traditional aristocratic class. The common people cannot participate in such an administration, and hence, it remains ‘aloof from political education. This system of administration is against the modern democratic outlook.
