This is very silly logic.
If say the public utility pipe and electricity cable that is the property of the utility company is in front of your house. People tap and steal from it, the tenant is held responsible?
Do you even understand what is a demarcation point or demilitarized zone(DMZ) between 2 country borders work?
At one side is TNB's property, the other side of the beyond the meter is the tenant's responsibility.
In this case, the TNB Smart Meter Input and Output serves as the Demarc Point.
If you don't understand go and Google "What Is A Demarc Point".
This one is gas line into residential homes.
*Only the green line after the demarc point is the responsibility of the property owner.This case sounds odd. I feel that the law firm which is representing these landlord tenants cases is incompetent and useless when it comes to consumer tribunals. I suggest they should boot him and find a more experienced one in handling their cases since their cases already involved millions.
Nothing to lose to spend a bit more on someone who can handle their cases better.
