1989Lasecki v. Traeger (1940), 374 Ill. 355, 359 , 29 N.E.2d 519 (statute conferring “broad and comprehensive” rulemaking power); Diversey Liquidating Corp. v. Neunkirchen (1939), 370 Ill. 523, 526 , 19 N.E.2d 363 (statute authorizing court to make all rules “necessary or expedient for the proper administration of justice in that court”).) The chief judge’s rulemaking and administrative duties under the Act do not violate the doctrine of separation of powers because they do not “ ‘infringe upon the inherent powers of the judiciary.’ ” People v. Taylor (1984), 102 Ill. 2d 201, 207 , 464 N.E.2d 1059

1989Finally, Bainter referred to our statement in People v. Davis (1982), 93 Ill. 2d 155, 161 , that this court must protect judicial powers from legislation, invalid under the separation of powers clause, that unduly infringes upon the inherent powers of the judiciary.

2010Such action does not offend the separation-of-powers clause of our constitution.” (Emphasis added.) First National Bank of Chicago v. King, 165 Ill. 2d 533, 542 (1995); see also People v. Rolfingsmeyer, 101 Ill. 2d 137, 140 (1984) (same); People v. Wells, 380 Ill. 347, 354 (1942) (same).

1995Such action does not offend the separation-of-powers clause of our constitution. ( People v. Rolfingsmeyer (1984), 101 Ill.2d 137, 140 , 77 Ill.Dec. 787 , 461 N.E.2d 410 .) Although the legislature cannot declare what shall be conclusive evidence ( Morrison v. Flowers (1923), 308 Ill. 189, 194 , 139 N.E. 10 ), the statute here does not purport to do so.

2008The court in West End applied the general rule that, “ ‘where authority has been conferred upon administrative agencies to perform functions of an executive nature, provisions for a trial de novo in courts of law violate the separation-of-powers principle’ ” (Devine, 181 Ill. 2d at 530 , quoting West End, 16 Ill. 2d at 525 ), held that the statute vested the courts with “ ‘a supervisory power which is not limited to a review of the administrative action but extends to a redetermination of factual issues’ ” (Devine, 181 Ill. 2d at 531 , quoting West End, 16 Ill. 2d at 525 ), and thus concluded
