It is observed by the Hon'ble Orissa High court as follows:
Both Sub−section (1) of Section 205, and Section 273, of the Cr PC provide for exemption of an accused from personal attendance; but they refer to different stages of the proceeding.
While the former deals with initial appearance of accused before the Magistrate who issues summons,
the latter deals with presence of accused at the trial and empowers the Presiding Officer to dispense with personal attendance of the Accused at the trial.
Sub−section (2) of Section 205 empowers the Magistrate to direct personal attendance of the accused if necessary at a later stage. Section 313, CrPC permits dispensation of personal attendance of the accused for the purpose of examination under the said Section, when in a summons case the Court has dispensed with personal attendance.
Section 273, incorporates the general principle that all evidence taken in course of the trial or other proceedings shall be taken in presence of the accused.
