When an administrative agency inexplicably departs from past practices, precedents, and/or established procedures, it abuses its discretion. Margalli-Olvera v. INS, 43 F.3d 345 (8th Cir. 1994) (BIA abused discretion by changing its position without explanation re: 212(c) tolling period); Gonzalez-Batoun v. INS, 791 F.2d 681 (9th Cir. 1986) (BIA abused discretion when it gave no reason for deviation from past practice); Salehpour v. INS, 761 F.2d 1442 (9th Cir. 1985) (abuse of discretion occurs where agency interpretation is inconsistent with its own regulations); Ke Zhen Zhao v. U. S. DOJ, 265 F.3d 83 (2d Cir. 2000) (an abuse of discretion may be found in those circumstances where the government inexplicably departs from established policies). In Sang Seup Shin v. INS, 750 F.2d 122, 125 (D.C. Cir. 1984), the court noted that although agencies like INS and EOIR do have broad discretion in adjustment cases, they cannot proceed "at whim, shedding [their] grace unevenly from case to case." An agency should explain its departures from settled policies, and it may not unaccountably hold relevant one day considerations it disregarded on another. The INS Operations Instruction 245.5(d) notes that the Service should strive to achieve "more uniform decisions with respect to the exercise of discretion in Section 245 cases." This issue is being adjudicated inconsistently within this District, and inconsistent with INS policy nationwide.
