swh, the cost of supporting the children is calculated by the Canadian government, not the parents. If the parents disagree with the amount, the parents need to make their case in a court. THIS parent chose to flee the country rather than make his case in court for a lower payment.
What false claims were made to the court?
The courts in HK based their residency determination on him having a Tung Chung address, not the work address. He claimed that the Tung Chung address was a clearical error by CX. He also claimed to the court in the US that he was a HK resident (supposedly to avoid liability in the US) and this claim was mentioned when he tried to convince the HK court that he wasn't a HK resident.
The government of Canada is demanding the money be paid, so IT must be fraudulent, in your eyes.
The court would not have had to guess the father's income if the father had voluntarily provided it to the court rather than fleeing the country and an arrest warrant.
The system may be broken, but ignoring it and the courts isn't the way to fix it.
