There is no need to revise the DA or Wages upon the revision by Government when you are paying the wages more than Minimum Wages. However, if it was a trend to revise the wages on every such increase in the past then you have to think of it.
It is a service condition in this case in my view and you can not discontinue it unilaterally.
One can differ with me.
