What happens if a person after any amount has become due from him, creates a charge on or parts with the property belonging to him or in his possession by way of sale, mortgage, or any other mode of transfer whatsoever of any of his properties in favour of any other person with the intention of defrauding the Government revenue

Such charge or transfer shall be void against any claim in respect of any tax or any other sum payable by the said person. However, such charge or transfer shall not be void, if it is made for adequate consideration and without notice of the pendency of such proceedings under the Act, or without notice of such tax or other sum payable by the said person, or with the previous permission of the proper officer.
