Negative aspect of federal system : 

The negative features of federal system are as follows: 

1. Federal government system is not suitable during crisis because during wars or internal crisis / danger, the union (the central government) government is unable to take any quick decision without the consent of states. 

2. This system is suitable for big countries only, not for small countries. 

3. In federal system, there are two types of governments of same kind and as a result of it, it is a wastage of money. 

4. In federal system, the citizens have dual citizenship. Hence, it poses a danger to the existence of federation (here union). 

5. In this system, there always persists the fear of legislative conflict because sometimes the centre and the state government both enact a law on the same subject. To settle this dispute, they have to go to the judiciary. 

6. This is a rigid governmental system in which amendments cannot be done easily. In this system the constitution is rigid, in which the process of amendment is difficult and rigid, which is different from the process of enactment of general laws. Hence, amendment cannot be made in it as per the requirements. 

7. In this system, the administrative powers are divided. This division of work creates laxity in administrative working. No administrative work is done smoothly due to this distribution of work between the central and state governments. 

8. Federal system of government is not folly successful in international field or policy. In this system, the government (centre) decides international policy under one process. The union has to depend on the cooperation of its units (states). Sometimes state governments come together and oppose the foreign policy of the union (central government). Therefore, sometimes, the union government is not folly successful in formation or implementation of international policy. 

On the basis of the above points, it can be concluded that despite of the several flaws in this system, in the modem times, this (federal) system is considered as an efficient and powerful system of government.
