I stumbled upon a website with the following paragraph:
MBIE has launched an investigation into claims Chinese galvanised steel coil imports have been dumped on the local market, causing "material injury" to New Zealand industry, and the case will end up on the table of newly appointed Commerce Minister Jacqui Dean.
I thought that sentence was grammatically wrong because the author should put the word "that" (as a conjunction) right after the word "claim". I don't see why the author could drop the conjunction. Is this a prevailing phenomenon in American or Australian English?
