(5) Consideration of asylum applications

(A) Procedures

The procedure established under paragraph (1) shall provide that—

(i) asylum cannot be granted until the identity of the applicant has been checked against all appropriate records or databases maintained by the Attorney General and by the Secretary of State, including the Automated Visa Lookout System, to determine any grounds on which the alien may be inadmissible to or deportable from the United States, or ineligible to apply for or be granted asylum;

(ii) in the absence of exceptional circumstances, the initial interview or hearing on the asylum application shall commence not later than 45 days after the date an application is filed;

(iii) in the absence of exceptional circumstances, final administrative adjudication of the asylum application, not including administrative appeal, shall be completed within 180 days after the date an application is filed;

(iv) any administrative appeal shall be filed within 30 days of a decision granting or denying asylum, or within 30 days of the completion of removal proceedings before an immigration judge under section 1229a of this title, whichever is later; and

(v) in the case of an applicant for asylum who fails without prior authorization or in the absence of exceptional circumstances to appear for an interview or hearing, including a hearing under section 1229a of this title, the application may be dismissed or the applicant may be otherwise sanctioned for such failure.

The Attorney General may provide by regulation for any other conditions or limitations on the consideration of an application for asylum not inconsistent with this chapter.

Guess Judge Sullivan found that the new regulations were "inconsistent" with this chapter.

The new question is, does the president have plenary power.
