"The could have kept the intrastate rates the same in spite of the regulations being imposed on the interstate rates. They simply chose not to."

You say you read this case?

Some carriers were inflating their interstate rates to offset their deflated intrastate rates, making intrastate-only carriers non-competitive. Since there was a direct relationship between the rates, Congress needed to regulate both.

The way I read the decision, they just said the carrier couldn't charge the interstate customers more than the intrastate customers. The carriers could have complied by lowering the interstate rates to match the intrastate rates. That would probably have resulted in them operating at a loss, but that decision was still in their hands.
