Justice R H Shukla stayed the order which convicted and sentenced the MP after he moved the HC against the order of Amreli Sessions Court.
Kachhadia had also moved a bail application which was also granted by the high court.
On Wednesday, Amreli Sessions Court had sentenced him to three years imprisonment for assaulting a doctor at a government hospital on January 1, 2013.
The court had, however, suspended the sentence for a month for Kachhadia and four other convicts to facilitate them to approach the HC against the conviction.
A doctor at Amreli Civil Hospital, Bhimjibhai Dabhi, was attacked by Kachhadia and others when he refused to tend to a patient who was a BJP worker's relative.
The patient, when asked by Dabhi to wait as he was looking after another patient, complained to Kachhadia who came to the hospital and allegedly thrashed Dabhi.
