I always have difficulty arriving at a useful conclusion as to the tendencies in terms of reports. I sometimes wonder why there aren't more complaints. I don't know whether it is because, as some would claim, the situation has improved, or because people aren't aware that they can lay complaints, or because people have become disillusioned and disabused of the value of making complaints, just take for granted that their language rights won't be respected, and shrug their shoulders.
I think the complaint mechanism should be seen primarily as a tool for getting government institutions who have obligations to correct their errors or their failures, as opposed to a barometer which demonstrates the overall success or failure of government institutions.
