Summarize the following court judgment. Civil Appeal No. 130 of 1956. Appeal from the judgment and decree dated the 10th March	 1952	 of the Allahabad High Court in Civil Writ No. 737 of 1951. G. C. Mathur and C. P. Lal	 for the appellant. section P. Sinha and section D. Sekhri	 for the respondent. September 30. The judgment of Das C. J.	 Venkatarama Aiyar	 Jafer Imam and Sarkar JJ. was delivered by Das C. J. Bose J. delivered a separate judgement. DAS C. J. This is an appeal filed under a certificate of fitness granted by the High Court of Judicature at Allahabad under articles 132 (1) and 133 (1) (c) of the Constitution. It is directed against the judgment and order of a Division Bench of the said High Court pronounced on March 10	 1952	 in Civil Misc. Writ No. 7376 of 1951 quashing the depart mental proceedings against the respondent and the orders passed 597 therein	 namely	 the order for his dismissal passed by the District Superintendent of Police on December 21	 1948	 the order of the Deputy Inspector General of Police passed on June 7	 1949	 dismissing his appeal against the order of his dismissal and the order of the Inspector General of Police dated April 22	1950 rejecting his application for revision. The judgment of the High Court also directed that	 if it were desired to proceed against the respondent	 the trial should be presided over by a person other than the District Superintendent of Police who gave evidence in the case and also passed the order of dismissal against the respondent and that it should be in strict conformity with the relevant Police Regulations. The respondent was a constable in the Uttar Pradesh Police Force and was	 at the material time	 officiating as a Head Constable and posted in the District of Fatenpur. In Decem ber	 1947	 sixty candidates had to be selected from the Police Force for training at tile Police Training College	 Moradabad. The respondent was sent up for selection from the District of Fatehpur. He	 however	 failed in the Hindi test and was not selected and sixty other candidates were selected for the training. On December 8	 1947 a letter	 purporting to have been issued from Lucknow	 was received in the U. P. Police Head Office at Allahabad intimating that the respondent had been select ed for training at the Police Training College. As there were only sixty vacancies and as sixty candidates had al ready been selected	 the Head Office people were led to make enquiries as to how this letter came to be issued from Lucknow. The letter having been placed before the Inspector General of Police	 Lucknow	he declared it to be a forgery. As the letter was ostensibly for the benefit of the respond ent	 it was naturally suspected that it must have been sent by or at his instance. On March 15	 1948 the respondent was placed under suspen sion. Under section 243 of the Government of India Act	 1935	 which was then in force	 the respondent	 who was in the police force	 was not governed by sub section (3) of section 240 which corresponds to article 311 (2) of 598 the Constitution but was governed by the (Act V of 1861) and the Regulations made thereunder by the State Government. Accordingly	 under section 7 of the read with Uttar Pradesh Police Regulations	 a departmental enquiry	 called a "trial" in the Regulations	 was started against the respondent. One Shri B. N. Bhalla	 the then District Superintendent of Police	 Fatehpur	 was deputed to hold the trial. He found the respondent guilty and on April 20	 1948 passed an order of dismissal against him. The respondent went up on appeal to the Deputy Inspector General of Police under Reg. That appeal was dismissed on June 7	 1949. The respondent then filed a revision application to the Inspector General of Police under Reg. 512. That application was also dismissed on April 22	 1950. Having exhausted all his remedies under the read with the Regulations thereunder the respondent on February 24	 1951	 filed a writ petition under article 226 of the Con stitution	 praying that the file of the applicant (now respondent) be called for and his dismissal be set aside and that he be given such further and other relief as he may	 in law	 be entitled to. The main point taken in the affidavit filed in support of the petition and urged before the High Court was that Shri B. N. Bhalla	 District Superintendent of Police	 who presided over the trial and as such had to come to a finding and to make an order	 also gave his own evi dence in the proceedings at two stages and had thus become disqualified from continuing as the judge	 as	 in the cir cumstances he was bound to be biased against the respondent. A preliminary objection was taken on behalf of the appellant State that the High Court had no power	 under article 226	 to deal with the order of dismissal which had been passed at a time when the Constitution of India had not come into force	 but the High Court rejected that plea as it took the view that the order of dismissal passed by the District Superin tendent of Police on December 20	 1948	 and the order of dismissal of the appeal passed by the Deputy Inspector General of Police on June 7	1949	 had not become final 599 until the Inspector General of Police	 on April 22	 1950	 made his order dismissing the revision application filed by the respondent under Reg. 512 and that as the last mentioned order had been passed after the Constitution had come into force	 and had	 by article 226	 vested powers in the High Court to issue prerogative writs	 the High Court had ample juris diction to exercise its newly acquired powers under that article. On the merits the High Court came to the conclu sion that the rules of natural justice and fair play had been disregarded	 in that the District Superintendent of Police had continued to preside over the trial even after it had become necessary for him to put on the record his own testimony as against that of another witness and it held that the presiding officer had	 in the circumstances	 become disqualified	 on the ground of bias	 from further acting as the presiding officer and that the departmental trial con ducted by him thereafter had become vitiated. The High Court	 accordingly	 quashed the proceedings and set aside the three several orders herein before mentioned. The appellant State on February 4	 1955	 obtained from the High Court a certificate of fitness under articles 132(1) and 133(1)(c) and hence the present appeal to this Court. It will be recalled that the forged letter of December 8	 1947	 was suspected to have been manufactured or sent by or at the instance of the respondent to further his interest. The case against the respondent was that the offending letter had been typed by one Shariful Hasan	 the typist attached to the office of the Superintendent of Police	 Fatehpur	 and	 therefore	 it was essential for the depart ment to establish that the respondent was in friendly rela tions with Shariful Hasan who was said to have typed the letter. Apparently in some preliminary enquiry and in the presence of Shri B. N. Bhalla one Mohammad Khalil	 a Head Constable	 had spoken about Shariful Hasan being very friendly with the respondent. But while giving his evidence at the departmental trial the said Mohammad Khalil denied having made any such statement. In the circumstances it became necessary to contradict him by the testimony of Shri B. N. Bhalla in whose presence 600 that witness had	 on a previous occasion	 stated that Shari ful Hasan was very friendly with the respondent. According ly Shri B. N. Bhalla had his testimony recorded by a Deputy Superintendent of Police. This was done at two stages	 namely	 once before the charges were framed and again after the framing of the charges. The respondent 's grievance is that Shri 'B. N. Bhalla	 who had thus become a witness in the case	 ought not to have further continued to act as the presiding officer and that his continuing to do so vitiated the trial and his order was a nullity. That Shri B. N. Bhalla had his own testimony recorded in the case is not denied. Indeed the appellant State	 in opposition to the respondent 's writ application	 filed an affidavit affirmed by Shri B. N. Bhalla	 paragraph 8 of which runs as follows: " 8. That the deponent gave his first statement on 13th October	 1948	 which was recorded by Shri Mohammad Sadiq	 Deputy Superintendent of Police before the charge and the second statement on 25th October	 1948	 which was recorded by another Deputy Superintendent of Police after the charge. One Head Constable	 Mohammad Khalil	 who was prosecution witness in the case	 when cross examined denied to have said that the applicant and Shariful Hasan were on friendly terms. He turned hostile and it became necessary for the deponent to depose about certain facts which had happened in his presence and which belied the testimony of Mohammad Khalil " The salient facts being thus admitted there can be no escape from the conclusion that Shri B. N. Bhalla should not have presided over the trial any longer. The point in issue was whether Shariful Hasan was in friendly relationship with the respondent. Mohammad Khalil had in his evidence at the trial denied having made any statement to this effect. Shri B. N. Bhalla gave evidence that Mohammad Khalil had in his presence admitted this friendship of Shariful Hasan with the respondent. Which of the two witnesses	 Mohammad Khalil and Shri B. N. Bhalla	 was to be believed was the duty of the person presiding over the trial to determine. Shri B. N. Bhalla was obviously 601 most ill suited to undertake that task. Having pitted his evidence against that of Mohammad Khalil Shri B. N. Bhalla vacated the Judge 's seat and entered the arena as a witness. The two roles could not obviously be played by one and the same person. lndeed Shri B. N. Bhalla himself realised it and accordingly bad his own evidence recorded on both the occasions by other high officers. It is futile to expect that he could	 in the circumstances	 hold the scale even. it is suggested that there might have been other evidence establishing the friendship between Shariful Hasan and the respondent and that the evidence of Shri B. N. Bhalla might not have been relied on or might Dot have been the deciding factor. There is nothing on the record before us to support this suggestion. But assuming that Shri B. N. Bhalla did not rely on his own evidence in preference to that of Mohammad Khalil a fact which is hard to believe	 especially in the face of his own affidavit quoted above the act of Shri B. N. Bhalla in having his own testimony recorded in the case indubitably evidences a state of mind which clearly discloses considerable bias against the respondent. If it shocks our notions of judicial propriety and fair play	 as indeed it does	 it was bound to make a deeper impression on the mind of the respondent as to the Unreality and futility of the proceedings Conducted in this fashion. We find ourselves in agreement with the High Court that the rules of natural justice were completely discarded and all canons of fair play were grievously violated by Shri B. N. Bhalla continuing to preside over the trial. Decision arrived at by such process and order founded on such decision cannot possibly be regarded as valid or binding. Learned counsel appearing for the appellant State then urges that	 assuming that any error	 irregularity or illegality had been committed by Shri B. N. Bhalla in the course of the trial held by him	 a writ application under article 226 was not the proper remedy for correcting the same. Reference is made to section 7 of the which	 subject to such rules as the State Government may make under the Act	 gives 602 power to certain specified Police Officers of high rank to dismiss	 suspend or reduce any Police Officer of the subordinate ranks whom they may think remiss or negligent in the discharge of his duties or unfit for the same. Regulation 508 of the Police Regulations made by the State of Uttar Pradesh provides for an appeal from the decision of the officer holding the trial. Likewise Reg. 512 confers on an officer whose appeal has been rejected to submit an application for revision to the authority next in rank above that by which his appeal has been rejected. The argument is that the and the Regulations made thereunder having provided for an appeal and a revision and having set up special forums with full powers and jurisdiction to correct the error	 irregularity or illegality touching jurisdiction	 procedure and the merits committed by the officer presiding over the trial	 such forums alone are competent to correct all such errors	 irregularities and illegalities. In this case admittedly the respondent preferred an appeal and then went up to the Inspector General of Police in revision. In the appeal and in the revision the respondent either took the plea of the breach of the rules of natural justice and fair play now complained of or he did not. The respondent knew the material facts and must be deemed to have been conscious of his legal rights in the matter and	 therefore	 if he failed to raise the objection before the officer who was dealing with his appeal or revision he cannot	 it is urged	 be permitted to do so for the first time on a writ petition under article 226 before the High Court	 as has been held by this Court in Manak Lal vs Dr. Prem Chand (1). On the other hand if he had raised the question in his grounds of appeal or in his revision petition and insisted on it at the hearing of his appeal or his revision application then the orders of dismissal of his appeal and his revision petition by authorities fully competent and having full powers and jurisdiction to decide the question must be taken as a rejection of that plea on its merits and as no error or irregularity or illegality is alleged to have been committed at the 603 stages of the appeal or the revision proceedings	 the High Court could not	 under article 226	 interfere in the matter. In support of this argument learned counsel for the appellant State relies upon the decision of this Court in Janardan Reddy vs The State of Hyderabad (1). In that case the petitioners were convicted by a special Tribunal of Hyderabad of murder and other offenses and sentenced to death by hanging. Their Convictions and sentences had been Confirmed by the Hyderabad High Court before January 26	 1950	 when the Constitution of India came into force. It was after the commencement of the Constitution that the petitioners applied to this Court under article 32 praying (1) for a writ in the nature of certiorari calling Upon the Government of Hyderabad and the Special Judge to produce the records of the case and to show cause why the convictions and sentences should not be quashed and (2) for a writ of prohibition directing the Government and the Special Judge not to execute the petitioners. Subsequently the petition was amended	 with the leave of the court	 by adding prayer (3) for a writ of habeas corpus. A number of points were raised before this Court. As regards the several points complaining of alleged illegality by reason of misjoinder of charges and the infliction of the sentence of death by hanging and not decapitation this Court at page 351 observed " But	 for the purpose of the present case	 it is 	sufficient to point out that even if we assume that there was some defect in the procedure followed at the trial	 it does not follow that the trial court acted without jurisdiction. There is a basic difference between want of jurisdiction	 and an illegal or irregular exercise of jurisdiction	 and our attention has not been drawn to any authority in which mere non compliance with the rules of procedure has been made a ground for granting one of the writs prayed for. In either case	 the defect	 if any	 can according to the procedure established by law be corrected only by a court of appeal or revision. Here the appellate court which was competent to deal with the matter has pronounced its judgment against the petitioners	 and the matter (1) ; 604 having been finally decided is not one to be reopened in a proceeding under article 32 of the Constitution. " As regards the prayers for writs of certiorari and prohibition it was held that the writs of certiorari and prohibition were hardly appropriate remedies in that case	 because they were usually directed to an inferior court	 but at the date when the High Court dealt with those cases and confirmed the convictions and sentences of the petitioners	 this Court was not in existence	 and at that point of time	 by no stretch of reasoning	 the High Court could be said to have been subordinate to this court. Then this Court went on to consider the remaining question	 namely	 whether after the commencement of the Constitution this Court could exercise its newly acquired jurisdiction under article 32 and issue a writ of habeas corpus as the detention of the petitioners was continuing even after the commencement of the Constitution. It was urged that it was open to the petitioners to prove by affidavit that the court which passed the order had acted without jurisdiction or in excess of it and the superior court was free to investigate the matter. After stating that a return that the persons were in detention in execution of sentences on indictment on criminal charges was a sufficient answer to the application for a writ of habeas corpus	 this Court proceeded at pages 366 367 to observe as follows: " Assuming however	 that it is open even in such cases to investigate the question of jurisdiction	 as was held in In re Authers (1)	 it appears to us that the learned judges who decided that case went too far in holding that notwithstanding the fact that the conviction and sentence had been upheld on appeal by a court of competent jurisdiction	 the mere fact that the trial court had acted without jurisdiction would justify interference	 treating the appellate order as a nullity. Evidently	 the Appellate Court	 in a case which properly comes before it on appeal	 is fully competent to decide whether the trial was with or without jurisdiction	 and it has jurisdiction to decide the matter rightly as well as wrongly. If it affirms the conviction (1) I. L.R. 22 B.D. 605 and thereby decides wrongly that the trial court had the jurisdiction to try and convict	 it cannot be said to have acted without jurisdiction	 and its order cannot be treated as a nullity. It is true that there is no such thing as the principle of constructive res judicata in a criminal case	 but there is such a principle as finality of judgments	 which applies to criminal as well as civil cases and is implicit in every system	 wherein provisions are to be found for correcting errors in appeal or in revision. " In the first place it must be noted that the two obser vations quoted from the decision of this Court on which reliance is placed on behalf of the appellant State were made in a case where the alleged error	 irregularity or illegality was committed by a special tribunal which had not merely the trappings of a court but was a court of law presided over by a judge with legal training and background and bound by rules of evidence and procedure laid down for it and the appeal from its decision lay before the highest and final court of the State a superior court of record. But orders made on departmental "trial" held by an officer in the department without any legal training and orders passed by his superior officers in the same department on appeal or in revision which	 in the words of Harries C.J. in Assistant Collector of Customs vs Soorajmull Nagarmull (1) were only in the nature of an appeal from Caesar to Caesar and which might not be regarded with any great confidence by persons brought before them can hardly be equated with reasonable propriety with the orders passed by the Special Tribunal and an appeal therefrom by the Hyderabad High Court with reference to which bodies alone the said observations had been made. In the next place it must be borne in mind that there is no rule	 with regard to certiorari as there is with mandamus	 that it will lie only where there is no other equally effective remedy. It is well established that	 provided the requisite grounds exist	 certiorari will lie although a right of appeal has been conferred by statute. (Halsbury 's Laws of England	 3rd Ed.	 Vol. 11	 p. 130 and the cases cited there). The fact (1) 	 46. 606 that the aggrieved party has another and adequate remedy may be taken into consideration by the superior court in arriving at a conclusion as to whether it should	 in exercise of its discretion	 issue a writ of certiorari to quash the proceedings and decisions of inferior courts subordinate to it and ordinarily the superior court will decline to interfere until the aggrieved party has exhausted his other statutory remedies	 if any. But this rule requiring the exhaustion of statutory remedies before the writ will be granted is a rule of policy	 convenience and discretion rather than a rule of law and instances are numerous where a writ of certiorari has been issued in spite of the fact that the aggrieved party had other adequate legal remedies. In the King vs Postmaster General Ex parte Carmichael (1) a certiorari was issued although the aggrieved party had an alternative remedy by way of appeal. It has been held that the superior court will readily issue a certiorari in a case where there has been a denial of natural justice before a court of summary jurisdiction. The case of Rex vs Wadsworth Justices Ex parte Read (2) is an authority in point. In that case a man had been convicted in a court of summary jurisdiction without giving him an opportunity of being heard. It was held that his remedy was not by a case stated or by an appeal before the quarter sessions but by application to the High Court for an order of certiorari to remove and quash the conviction. At page 284 Viscount Caldecote C.J. observed: " It remains to consider the argument that the remedy of certiorari is not open to the applicant because others were available. It would be ludicrous in such a case as the present for the convicted person to ask for a case to be stated. It would mean asking this court to consider as a question of law whether justices were right in convicting a man without hearing his evidence. That is so extravagant an argument as not to merit a moment 's consideration. As to the right of appeal to quarter sessions	 it may be that the applicant could have had his remedy if he (1)[1928] 1 K.B. 201. (2) 607 had pursued that course	 but I am not aware of any reason why	 if in such circumstances as these	 he preferred to apply for an order of certiorari to quash his conviction	 the court should be debarred from granting his application." Likewise in Khurshed Modi vs Rent Controller	 Bombay (1)	 it was held that the High Court would not refuse to issue a writ of certiorari merely because there was a right of appeal. It was recognized that ordinarily the High Court would require the petitioner to have recourse to his ordinary remedies	 but if it found that there had been a breach of fundamental principles of justice	 the High Court would certainly not hesitate to issue the writ of certiorari. To the same effect are the following observations of Harries C.J. in Assistant Collector of Customs vs Soorajmull Nagarmul (2) at page 470: " There can	 I think	 be no doubt that Court can refuse to issue a certiorari if the petitioner has other remedies equally convenient and effective. But it appears to me that there can be cases where the court can and should issue a certiorari even where such alternative remedies are available. Where a Court or Tribunal	 which is called upon to exercise judicial or quasi judicial functions discards all rules of natural justice and arrives at a decision contrary to all accepted principles of justice then it appears to me that the court can and must interfere. " It has also been held that a litigant who has lost his right of appeal or has failed to perfect an appeal by no fault of his own may in a proper case obtain a review by certiorari. (See Corpus Juris Secundum Vol. 14	 article 40	 p. 189). If	 therefore	 the existence of other adequate legal remedies is not per se a bar to the issue of a writ of certiorari and if in a proper case it may be the duty of the superior court to issue a writ of certiorari to correct the errors of an inferior court or tribunal called upon to exercise judicial or quasi judicial functions and not to relegate the petitioner to other legal remedies available to him and if the superior court can in a proper case exercise its jurisdiction 1) A.I.R. 1 Bom. 6. 2) 608 in favour of a petitioner who has allowed the time to appeal to expire or has not perfected his appeal	 e.g.	 by furnishing security required by the statute	 should it then be laid down as an inflexible rule of law that the superior court must deny the writ when an inferior court or tribunal by discarding all principles of natural justice and all accepted rules of procedure arrived at a conclusion which shocks the sense of justice and fair play merely because such decision has been upheld by another inferior court or tribunal on appeal or revision? The case of In re	 Authers (1) referred to in Janardan Reddy 's case	 (2) furnishes the answer. There the manager of a club was convicted under a certain statute for selling beer by retail without an excise retail license. Subsequently he was convicted of selling intoxicating liquor	 namely	 beer without a license under another statute. Upon hearing of the later charge the magistrate treated it as a second offence and imposed a full penalty authorised in the case of a second offence by the latter statute. His appeal to the quarter sessions having been dismissed	 he applied for a writ of habeas corpus and it was granted by the King 's Bench Division on the ground that the magistrate could not treat the later offence as a second offence	 because it was not a second offence under the Act under which he was convicted for the second time. Evidently the point was taken that if there had been any error	 irregularity or illegality committed by the magistrate	 the quarter sessions could have on appeal corrected the same and that the quarter sessions having dismissed the appeal the court of Queen 's Bench Division could not issue the writ of habeas corpus. This was repelled by the following observation of Hawkins J.: " This is true as a fact	 but it puts the prosecution in no better position	 for if the magistrate had no power to give himself jurisdiction by finding that there had been a first offence where there had been none	 the justices could not give it to him. " On the authorities referred to above it appears to us that there may conceivably be cases and the instant (1) 889 (2) ; 609 case is in point where the error	 irregularity or illegality touching jurisdiction or procedure committed by an inferior court or tribunal of first instance is so patent and loudly obtrusive that it leaves on its decision an indelible stamp of infirmity or vice which cannot be obliterated or cured on appeal or revision. If an inferior court or tribunal of first instance acts wholly without jurisdiction or patently in excess of jurisdiction or manifestly conducts the proceedings before it in a manner which is contrary to the rules of natural justice and all accepted rules of procedure and which offends the superior court 's sense of fair play the superior court may	 we think	 quite properly exercise its power to issue the prerogative writ of certiorari to correct the error of the court or tribunal of first instance	 even if an appeal to another inferior court or tribunal was available and recourse was not had to it or if recourse was had to it confirmed what ex facie was a nullity for reasons aforementioned. This would be so all the more if the tribunals holding the original trial and the tribunals hearing the appeal or revision were merely departmental tribunals composed of persons belonging to the departmental hierarchy without adequate legal training and background and whose glaring lapses occasionally come to our notice. The superior court will ordinarily decline to interfere by issuing certiorari and all we say is that in a proper case of the kind mentioned above it has the power to do so and may and should exercise it. We say no more than that. Learned counsel for the appellant State next urges that because the order of dismissal was passed by the District Superintendent of Police on December 20	 1948	 and the order dismissing the appeal was passed by the Deputy Inspector General of Police on June 7	 1949	 both of which were before the commencement of the Constitution	 the High Court could not exercise its powers under article 226 to quash those orders. This argument is countered by the respondent by the argument that the dismissal order of December 20	 1948	 did not become final until after the Inspector General of Police had dismissed the revision	 610 application on April 22	1950	 that is to say	 after the Constitution came into force	 and	 therefore	 the High Court had ample power to quash all the three orders. It is not disputed that our Constitution is prospective in its application and has no retrospective operation except where the contrary has been expressly provided for. It has been held in a series of decisions of the High Courts	 some of which are referred to in the judgment under appeal	 that article 226 and article 227 have no retrospective operation and transactions which are past and closed and the rights and liabilities which have accrued and vested would remain unaffected. The correctness of this principle has not been questioned by the High Court when dealing with the present case and has not been disputed before us. It is	 therefore	 conceded that if the matter had rested with the order of dismissal passed by the District Superintendent of Police on April 20	 1948	 and the order passed by the Deputy Inspector General of Police on June 7	 1949	 dismissing the appeal and confirming the order for the dismissal of the respondent	 an application for a writ under article 226 would not lie in this High Court to set aside those orders as this was not one of the High Courts that had writ jurisdiction before the Constitution. It is	 however	 contended that the order of dismissal dated April 20	 1948	 had merged in the order passed on appeal on June 7	1949	 and that both the orders merged in the order passed by the Inspector General of Police on April 22	 1950	 on the revision application. It is said that the revisional jurisdiction is a part of the appellate jurisdiction and the principle on which a decree of the court of first instance in a civil suit merges in the decree on appeal applies with equal force to an order made on an application for revision and consequently both the orders passed by the District Superintendent of Police and that passed on appeal by the Deputy Inspector General of Police merged in the order passed on revision by the Inspector General of Police on April 22	 1950. To put it shortly	 the contention of the respondent is that the order of dismissal passed on April 20	became final only on the passing of the order in 611 revision on April 22	 1950	 and as that order was passed after the date of the commencement of the Constitution	 its validity could be called in question on an application under article 226. There appear to be two answers to the foregoing contention. As we have already observed an order of dismissal passed on a departmental enquiry by an officer in the department and an order passed by another officer next higher in rank dis missing an appeal therefrom and an order rejecting an application for revision by the head of the department can hardly be equated with any propriety with decrees made in a civil suit under the Code of Civil Procedure by the court of first instance and the decree dismissing the appeal there from by an appeal court and the order dismissing the revision petition by a yet higher court	 as has been sought to be done by the High Court in this case	 because the departmental tribunals of the first instance or on appeal or revision are not regular courts manned by persons trained in law although they may have the trappings of the courts of law. The danger of so doing is evident from what has happened in the very case now before us. In the next place	 while it is true that a decree of a court of first instance may be said to merge in the decree passed on appeal there from or even in the order passed in revision	 it does so only for certain purposes	 namely	 for the purposes of computing the period of limitation for execution of the decree as in Batuk Nath vs Munni Dei(1)	 or for computing the period of limitation for an application for final decree in a mortgage suit as in Jowad Hussain vs Gendan Singh (2). But	 as pointed out by Sir Lawrence Jenkins in delivering the judgment of the Privy Council in Juscurn Boid vs Prithichand Lal (3)	 whatever be the theory under other systems of law	 under the Indian Law and ' procedure an original decree is not suspended by the presentation of an appeal nor is its operation interrupted where the (1) (1914) L.R. 41 I.A. 104. (2) (1926) L.R. 53 1 A. 197. (3) (1918) L.R. 46 I.A	 Cal. 670	 678 679. 612 decree on appeal is merely one of dismissal. There is nothing in the Indian Law to warrant the suggestion that the decree or order of the court or tribunal of the first instance becomes final only on the termination of all proceedings by 'way of appeal or revision. The filing of the appeal or revision may put the decree or order in jeopardy but until it is reversed or modified it remains effective. In that view of the matter the original order of dismissal passed on April 20	 1948	 was not suspended by the presentation of appeal by the respondent nor was its operation interrupted when the Deputy Inspector General of Police simply dismissed the appeal from that order or the Inspector General simply dismissed the application for revision. The original order of dismissal	 if there were no inherent infirmities in it	 was operative on its own strength and it did not gain any greater efficacy from the subsequent orders of dismissal of the appeal or the revision except for the specific purposes hereinbelow mentioned. That order of dismissal having been passed before the Constitution and rights having accrued to the appellant State and liabilities having attached to the respondent before the Constitution came into force	 the subsequent conferment of jurisdiction and powers on the High Court can have no retrospective operation on such rights and liabilities. Even if the order of dismissal of the respondent was a nullity on the ground that it was passed by disregarding the rules of natural justice	 the High Court could not properly be asked to exercise its newly acquired jurisdiction and powers under article 226 to correct errors	 irregularities or illegalities committed by the inferior departmental tribunal before the commencement of the Constitution	 for then there will be no limit to its going backward and that will certainly amount to giving the provisions of article 226 a retroactive operation. This aspect of the matter does not appear to have been pressed in the High Court or adverted to by it. It is only on this ground that we are constrained	 not without regret	 to accept this appeal. The appeal is	 therefore	 allowed	 but in the circumstances of the case we make no order as to costs. 613 BOSE J. With great respect I am unable to agree. I respectfully agree with my Lord that Janardan Reddy 's case (1) must not be construed to mean that a High Court can never interfere under article 226 once a competent Court of appeal has finally decided whether a Court subordinate to it has jurisdiction or not in a given matter. I also accept the position that the Constitution is not retrospective and that the Courts cannot exercise any new jurisdiction and powers conferred by it to reopen decisions and orders that had become final before it came into being. But I cannot agree that is the case here. The very wide powers conferred on the High Courts by article 226	 and on this Court by article 136	 were given in order to ensure that justice is done in this land and that the Rule of Law prevails. I see no reason why any narrow or ultra technical restrictions should be placed on them. Justice should	 in my opinion	 be administered in our Courts in a common sense liberal way and be broad based on human values rather than on narrow and restricted considerations hedged round with hairsplitting technicalities. What is the position here ? What would have been the result if the order of April 20	 1948	 dismissing the respondent had been passed after the Constitution instead of before it ? At what point of time would the High Court have entertained a petition under article 226 ? I think it is elementary that	 save in exceptional cases	 the Courts will not interfere under article 226 until all normal remedies available to a petitioner have been exhausted. The normal remedies in a case of this kind are appeal and revision. It is true that on a matter of jurisdiction	 or on a question that goes to the root of the case	 the High Courts can entertain a petition at an earlier stage but they are not bound to do so and a petition would not be thrown out because the petitioner had done that which the Courts usually direct him to do	 namely	 to exhaust his normal remedies before invoking an extraordinary jurisdiction. Therefore	 if this order of dismissal had (1)[1951] S.C.R.344. 614 been made after the Constitution	 the petitioner would have been expected to pursue his remedies of appeal and revision first and could not have come to the High Court in the ordinary way until he had exhausted them; and having come at that stage he could not have been turned away unheard on the ground that he was out of time because his grievance was against the original order. The very decisions to which my Lord has referred establish that for these purposes	 at any rate	 the earlier orders would merge in the final one. But I am not basing on technicalities. What is plain to me is that if this order of dismissal had been made after the Constitution	 the petitioner would have been entitled to wait for the final order (and in the ordinary way would have been bound to wait) before coming to the High Court. Why is the position any different because he has done before the Constitution exactly what he would have been expected	 and in the ordinary course bound	 to do after it ? The final order was passed after the Constitution on April 22	 1950. It is true that if it had been passed before the Constitution came into force on January 26	 1950	 the petitioner would have had no remedy in the Courts. But the Constitution breathed fresh life into this land and conferred precious rights and privileges that were not there before. Why should they be viewed narrowly ? Why should not that which would have been regarded as still pending for present purposes	 if all had been done after the Constitution	 be construed in any different way when the final act	 which is the decisive one for these purposes	 was done after it ? I regard it as unduly narrow and restrictive to equate these broad based constitutional privileges to highly technical procedural decisions dealing with limitation and the merger of decrees. The question to my mind is not whether there has been merger but whether those proceedings can	 on any broad and commons view	 be regarded as still pending for the purposes of article 226. If they would be so regarded when all is done after the Constitution (and about that I have no doubt)	 what conceivable justification is there for 615 holding that they cannot in this case just because a part of the process had started before it ? The principle that new rights conferred under the Constitution can be used in pending proceedings with devastating effect has been accepted by this Court in many cases. In Lachmandas Kewalram Ahuja vs The State of Bombay (1) my Lord the Chief Justice	 delivering the judgment of the Court	 pointed out at page 734 that though the Legislature had power to take away normal rights of	 among other things	 transfer and revision in a criminal case before the Constitution	 that kind of legislation became bad after the Constitution	 even if it bad been enacted before	 because of the new rights conferred by article 14. The principle was also applied in Shree Meenakshi Mills Ltd. vs Sri A. V. Visvanatha Sastri (2)	 Dhirendra Kumar Mandal vs The Superintendent and Remembrance of Legal Affairs to the Government of West Bengal(3)	 Habeeb Mohamed vs The State of Hyderabad(4) Syed Casim Razvi vs The State of Hyderabad (5) and Keshavan Madhava Menon vs The State of Bombay (6). These cases are not exactly in point but the principle is there and it is that principle that I invoke here. On the merits I am clear that the appeal should be dismissed. In the first place	 this Court	 following the English decisions	 has decided in Manak Lal vs Dr. Prem Chand Singhvi (7) that the principles of natural justice must be observed not only by Courts proper but also by " all tribunals and bodies which are given jurisdiction to determine judicially the rights of parties"; and if they are not observed	 the decision is vitiated. So that is now beyond controversy. Next	 there can	 I think	 be no doubt that the District Superintendent of Police	 who conducted the departmental trial and found the respondent guilty	 acted in a judicial capacity. The Departmental Rules that require an enquiry in such cases call the 2	0.7 (1) [1952) S.C.R. 710. (2) 	 798. (3) ; 	237. (4) ; (5) (6) [1951] 9.C.R. 228. (7) ; 	 429. 616 proceedings a trial and the procedure 	set out in them indicates the judicial nature of the enquiry. So that condition is also fulfilled. Then	 thirdly	 were the principles of natural justice ignored in this case ? That also is	 I think	 settled by authority. What happened here ? The District Superintendent of Police examined a certain witness in the course of the enquiry. It seems that witness 's evidence was considered a vital link in the chain of evidence against the respondent. The District Superintendent of Police reached the conclusion that the witness had turned hostile. He may have been right about that	 but he also considered it necessary to refute this evidence and make good the lacunas by bringing other material on record. Apparently	 no other witness was available	 so the District Superintendent of Police	 who seems to have had personal knowledge about the facts	 stepped down from the Bench and got his testimony recorded by another authority	 once before charge and again after charge	 and each time	 after that was done	 stepped back on to the Bench in order solemnly to decide whether he should believe his own testimony in preference to that of the witness who	 in his judgment	 had committed perjury and gone back on the truth. It hardly matters whether this was done in good faith or whether the truth lay that way because the spectacle of a judge hopping on and off the bench to act first as judge	 then as witness	 then as judge again to determine whether he should believe himself in preference to another witness	 is startling to say the least. It would	 doubtless delight the hearts of a Gilbert and Sullivan Comic Opera audience but will hardly inspire public confidence in the fairness and impartiality of departmental trials; and certainly not in the mind of the respondent. Even before the Constitution	 departmental trials were instituted to instil a sense of security in the services and inspire confidence in the public about the treatment accorded to government servants. The question in these cases is always: Whether it is likely to produce	 in the minds	 of the litigant or the public at large a reasonable doubt 617 about the fairness of the administration of justice. (Manak Lal vs Dr. Prem Chand) (1). One of the English cases relied on by this Court in the case just cited was the House of Lords ' decision in Frome United Breweries CO. vs Bath Justices(2). At page 600 Lord Atkinson cited an instance which is almost on all fours with the present case. He said: " It could not possibly have been intended by this statute to authorise a practice which would	 I think	 be inconsistent with the proper administration of justice namely	 that a licensing justice	 one of the members of the compensation authority	 should	 on a given occasion	 descend from the Bench	 give his evidence on oath	 and then return to his place upon the Bench to give a decision possibly based on his own evidence. " The matter is	 as I said	 covered by authority and I need say no more except that	 even if it were not	 I would have had no hesitation in reaching the same conclusion. Some question arose about waiver. If the respondent	 knowing his rights	 had acquiesced in the continuance of the trial despite this defect	 then	 of course	 he would not have been allowed to complain at a later stage. I do not know whether he was represented by counsel in the enquiry or whether	 if he was not	 he was aware that this kind of action vitiated the proceedings; nor do I know whether he protested and took the point in the appeal and revision. Those papers have not been filed. But I do know that waiver is not raised in the grounds of appeal to this Court nor is the point taken in the appellant 's statement of the case. As this is a question of fact	 I	 for one	 would not allow it to be urged at this stage. I would dismiss the appeal. ORDER. In accordance with the opinion of the majority	 the appeal is allowed.

A departmental enquiry against the respondent	 a Head Con stable	 was held by the District Superintendent of Police. During the enquiry the District Superintendent of Police himself became a witness and gave evidence at two stages against the respondent	 his statement being recorded by a Deputy Superintendent of Police. The District Superintend ent of Police then found the respondent guilty and on April 20	 1948	 passed an order of dismissal against him. The respondent went up in appeal to the Deputy Inspector General of Police but the appeal was dismissed on May 7	 1949. The respondent then filed a revision application to the Inspec tor General of Police which was also dismissed on April 22	 1950. Thereupon	 the respondent filed a writ petition under article 226 of the Constitution before the High Court praying for the setting aside of the order of dismissal. The High Court held that the rules of natural justice and fair play had been disregarded and accordingly	 quashed the proceed ings and set aside the three several orders. The State obtained a certificate of fitness and appealed. Held	 (percuriam) that the District Superintendent of Police who had acted both as the judge and as a witness had dis qualified himself from presiding over the enquiry. The procedure adopted was contrary to the rules of natural justice and fair play. Decisions and orders based on such procedure are invalid and not binding. There is no rule with regard to certiorari	 as there is with mandamus	 that it will lie only where there is no other equally effective remedy. The existence of another adequate remedy may be taken into consideration in the exercise of the discretion. If an inferior Court or tribunal of first instance acts without jurisdiction or in excess of it or contrary to the rules of natural justice	 the superior Court may quite properly issue a writ of certiorari to correct the error	 even if an appeal to another inferior Court or tribu nal was available	 whether recourse was or was not had to it. This would be so all the more in the case of departmen tal tribunals composed of persons without adequate legal training and background. 76 596 Janardan Reddy vs The State of Hyderabad	 ; referred to.

Bose	 J.	 dissenting) that article 226 of the Constitution is not retrospective and the High Court could not exercise its powers under article 226 to quash the order of dismissal passed before the commencement of the Constitu tion. It is wrong to say that the order of dismissal passed on April 20	 1948	 merged in the order in the appeal dated May 7	 1949	 and the two orders merged in the order in the revision dated April 22	 1950	 or that the original order of dismissal became final only on the passing of the order in revision. The original order of dismissal was operative on its own strength. Per Bose	 J. The High Court had jurisdiction to quash all the orders	 as the proceedings should be regarded as still pending till the order in revision was passed on April 22	 195o. The District Superintendent of Police was acting in a judicial capacity and was bound to observe principles of natural justice. These principles he ignored.
