A bench headed by Justice Vikramajit Sen dismissed Mayawati's plea that sought a restraint order on assessing her income, claiming that a prior mandatory notice was not served on her.
The court, while passing the order, said Mayawati had failed to prove her case.
She had earlier on Wednesday, Jan 7 snubbed the income tax department for reassessing her income without serving her notice.
The IT department, however, denied her contentions.
The High Court also charged Mayawati with evading tax for the assessment year 2003-04. This case was filed by the IT department against Income Tax Appellate Tribunal's decision that gave her a clean chit.
The Nov 2007 Tribunal had held that gifts worth Rs 65 lakh were given to Mayawati by her supporters out of love and affection and they were not taxable income.
The Centre, however, had maintained that the cash and property presented to the Bahujan Samaj Party leader should be treated as part of her annual taxable income.&13;&13;
