You can fight.
But he cannot fight, if it was denied due to either fraudulent activity or due ability-to-pay issue. MTR always requires new evidence. I don't see any possible new evidence if it is denied due to above reasons. MTR can be filed only if it was revoked by company (original sponsorer) and beneficiary used A21 meanwhile. I don't think this is the case here.
