In re Marrama, 549 U.S. 365, 127 S.Ct. 1105 (2007)
    Debtor forfeited his right to convert his case to chapter 13 where he did not qualify as a debtor because of his bad faith concealment of assets

In re Lynch, 363 B.R. 101 (9th Cir. BAP 2007)
    Trustee should not have been compelled to abandon property.  Even though the debtor valued the property at 560,000 as of the date of the filing of the  chapter 13 petition, and the  plan  was confirmed without objection, that valuation was not binding on the trustee under § 348(f)(1), since no implicit valuation occurred.  However, the relevant valuation date was the petition date, not the conversion date (absent a showing of bad faith.

In re Fowler, 394 F.3d 1208 (9th Cir. 2005)
    “We hold that § 348(d) requires that postpetition employment tax debt, incurred as an administrative expense of a Chapter 11 bankruptcy estate, retains its first priority administrative expense status upon conversion to a Chapter 13 bankruptcy plan.  Section 1305 is not in conflict with this holding because it does not govern the priority of the postpetition claims it allows into the bankruptcy.”

    Conversion from chapter 11 to chapter 7 was warranted where corporation charge with responsibility for liquidating bankruptcy estate caused unreasonable delay by failing to account to investors.

In re Johnston, 149 B.R. 158 (9th Cir. B.A.P. 1992)
