Immigration bureau's power under CA 613
The Bureau of Immigration is the agency that can best determine whether a
petitioner violated certain provisions of C.A. No. 613, as amended. In this
jurisdiction, courts will not interfere in matters which are addressed to the
sound discretion of government agencies entrusted with the regulation of
activities coming under the special technical knowledge and training of such
agencies. By reason of the special knowledge and expertise of administrative
departments over matters falling within their jurisdiction, they are in a better
position to pass judgment thereon and their findings of fact in that regard are
generally accorded respect, if not finality, by the courts. (Tze Sun Wong
v. Kenny Wong, G.R. No. 180364, December 3, 2014)
