New York Laws
Article 55 - Appeals Generally
5520 - Omissions; Appeal by Improper Method.

(b) Appeal by permission instead of as of right. An appeal taken by
permission shall not be dismissed upon the ground that the appeal would
lie as of right and was not taken within the time limited for an appeal
as of right, provided the motion for permission was made within the time
limited for taking the appeal.
(c) Defects in form. Where a notice of appeal is premature or contains
an inaccurate description of the judgment or order appealed from, the
appellate court, in its discretion, when the interests of justice so
demand, may treat such a notice as valid.
