AND SOCIAL FIELDS ), ARTICLE 56 ( RECONVERSION AND READAPTATION AIDS ) AND ARTICLE 53 ( THE MAKING OF FINANCIAL ARRANGEMENTS ).
60 IN PURSUANCE OF THAT PRINCIPLE THE COMMISSION CONSIDERED TAKING NON-COMPULSORY MEASURES DESIGNED TO BRING THE SUPPLY OF IRON AND STEEL PRODUCTS MORE INTO LINE WITH DEMAND ; THOSE MEASURES - AS ALREADY EXPLAINED - RELIED INTER ALIA UPON COMMITMENTS BY COMMUNITY STEEL UNDERTAKINGS TO ADHERE TO THE DELIVERY LIMITS SET BY THE COMMISSION AND NOTIFIED TO EACH UNDERTAKING OR GROUP OF UNDERTAKINGS . IN CONTRAST TO THE POSITION FOR OTHER ROLLED PRODUCTS , FOR WHICH VOLUNTARY COMMITMENTS TO REDUCE PRODUCTION COVERED 90% OF THE AMOUNT FIXED BY THE COMMISSION , ONLY 50% OF THE DELIVERY TARGET SET FOR CONCRETE REINFORCEMENT BARS WAS COVERED BY VOLUNTARY COMMITMENTS , WHICH FIGURE WAS CLEARLY INSUFFICIENT TO ENABLE THE SECTOR TO ACHIEVE THE RECOVERY HOPED FOR . THAT LED TO A MORE PRONOUNCED DETERIORATION OF THE MARKET FOR CONCRETE REINFORCEMENT BARS . THUS THE NEED FOR A COMPULSORY SYSTEM OF PRICES FOR CONCRETE REINFORCEMENT BARS WAS DEMONSTRATED BY THE FAILURE OF THE SYSTEM OF VOLUNTARY COMMITMENTS AIMED AT REDUCING PRODUCTION , WHILST FOR THE OTHER ROLLED PRODUCTS THE COMMISSION PUBLISHED GUIDANCE PRICES ( OFFICIAL JOURNAL L 114 OF 5 MAY 1977 , P . 18 ).
61 CERTAIN APPLICANTS , IN PARTICULAR RUMI ( CASE 263/78 ), CONSIDER THAT THE COMMISSION MADE AN ERRONEOUS ASSESSMENT OF THE ECONOMIC SITUATION AMOUNTING TO A MANIFEST FAILURE TO OBSERVE THE RULES OF THE TREATY BY INTRODUCING A MINIMUM PRICES SCHEME WHEN ' ' IT SHOULD HAVE HAD RECOURSE TO ARTICLE 58 OF THE TREATY AND SET UP A SCHEME OF PRODUCTION QUOTAS IN CONJUNCTION WITH A RANGE OF ANCILLARY MEASURES ' ' .
62 IN ORDER TO REJECT THIS COMPLAINT OF FAILURE TO INTERVENE DIRECTLY IN THE FIELD OF PRODUCTION , IT IS SUFFICIENT TO NOTE THAT ARTICLE 58 MAKES THE INTRODUCTION OF A BINDING SYSTEM OF PRODUCTION QUOTAS CONDITIONAL UPON A FINDING THAT THE MEANS OF ACTION PROVIDED FOR IN ARTICLE 57 ARE NOT SUFFICIENT TO DEAL WITH THE CRISIS . THOSE INDIRECT MEANS OF ACTION INCLUDE INTERVENTION IN REGARD TO PRICES AS PROVIDED FOR IN THE TREATY AND THEREFORE THE INTRODUCTION OF A MINIMUM PRICES SCHEME UNDER ARTICLE 61 ( B ).
63 THUS , WITHOUT ITS BEING NECESSARY TO HAVE RECOURSE TO THE ARGUMENT THAT IN THIS FIELD THE COMMISSION HAS A WIDE DISCRETIONARY POWER AS REGARDS ECONOMIC CHOICES WHICH MAY BE CHALLENGED ONLY IF IT HAS MISUSED ITS POWERS OR MANIFESTLY FAILED TO OBSERVE THE PROVISIONS OF THE TREATY , IT IS SUFFICIENT TO OBSERVE , IN ORDER TO DECLARE THIS SUBMISSION UNFOUNDED , THAT THE COMMISSION COULD BE REQUIRED TO INTRODUCE A SYSTEM OF PRODUCTION QUOTAS ONLY IF IT WERE ESTABLISHED THAT THE CRISIS COULD NOT BE REMEDIED BY MEANS OF , INTER ALIA , INTERVENTION IN REGARD TO PRICES .
64 CONSEQUENTLY , BY WEIGHING THE DISADVANTAGES OF THE MINIMUM PRICES SCHEME AGAINST THE NECESSITY FOR THE MEASURE
