As of December 1, 2016, amendments to the Federal Rules of Civil Procedure took effect, including the amendment of Rule 6(d), which governs additional time after certain kinds of service. The new Rule 6(d) removes service by electronic means under Rule 5(b)(2)(E) from the modes of service that allow three days to be added after the prescribed period to respond expires. The new Rule 6(d) reads as follows:
(d) Additional Time After Certain Kinds of Service. When a party may or must act within a specified time after being served and service is made under Rule 5(b)(2)(C) (mail), (D) (leaving with the clerk), or (F) (other means consented to), 3 days are added after the period would otherwise expire under Rule 6(a).
