                           the Code. In addition, the Member shall give due consideration to

                           3 A Member which is not in a position to implement
                           the rights and principles in the manner set out in Part A of the Code
                           may, unless expressly provided otherwise in this Convention, implement
                           Part A through provisions in its laws and regulations or other measures
                           which are substantially equivalent to the provisions of Part A.

                           Article, any law, regulation, collective agreement or other implementing
                           measure shall be considered to be substantially equivalent, in the
                           context of this Convention, if the Member satisfies itself that:

                                 (a) it is conducive to the full achievement of
                                 the general object and purpose of the provision or provisions of Part
                                 A of the Code concerned; and
                              
                              
                              
                            
                           - 
                              
                              
                              
                                 (b) it gives effect to the provision or provisions
