Disadvantages are as follows:
- Distribution of powers between centre and state Government leads to many conflicts. Because evey state has a separate jurisdiction of rights.
- The Constitution being rigid cannot be adjusted to the fast changing conditions.
- The state govt sometimes place hindrance in the foreign policy of the centre.
- Lack of uniformity in administration because of duel government that is one at the centre and the other in the states.
- Threats to national unity because sometimes the units are allowed to secede. This is called the Right of self determination.
- As compared to unitary govt, federal govt is weaker because there is division of powers in it. In unitary, there is centralisation of powers; hence the govt is strong and the administration is stable.
