Directors of defaulting companies to be liable to pay tax etc.

Notwithstanding anything contained in any other law, where any tax assessed or penalty imposed under this Act on a company cannot be recovered by reason of the company having gone into liquidation or for any other reason, then every person, who was Director of such company at any time during the relevant period for which the tax is due or in respect of which the default for which the penalty is imposed was committed, shall be jointly and severally liable for the payment of such tax and penalty unless he proves that the non-payment or non-recovery cannot be attributed to any neglect, mis-feasance or breach of duty on his part in relation to the affairs of the company.
