The other officials
When a country is ruled by a government with a clear majority in Parliament, the administration has the main responsibility for any reforms that must be carried out. However, it cannot be held entirely responsible for their fate because reforms cannot be successful through their imposition alone.
Necessary changes must be embraced – or at least not sabotaged – by the other official figures representing the state as well, whether they are university rectors or judges.
If prominent and influential public officials are mainly concerned about holding on to their seat and tenure, and if the demands they make are exhausted in claiming more funds from the state budget, then no major change can ever be expected to proceed successfully.
