Kerala PSC scam

Like in many other fields Kerala thus secured a unique position among other Indian States with appointment in government service by producing fake Joining order and advice memo of the Kerala Public Service Commission. If all were rotten, why the PSC alone dither from it?
I sympathise with those candidates applied for PSC test, studied much, travelled miles and spent a lot to get a berth the PSC rank list. Why the government restrict its enquiry in Revenue Department alone? Extend it Home and other departments, where there are apparently many without requisite qualifications. The legitimate village assistants and LD Clerks in Revenue Department would be viewed with suspicion hereinafter.
