be included as authorized signatories for submission of notice for erection of building in the relevant provisions of the Acts of 1994 and not limited to Structural Engineers. That challenge, however, would not survive for consideration in view of the amendment effected in the respective enactments of 1994 in the year 2007, vide proviso. That not only enabled Structural Engineers to be authorized signatory on the notice for erection of building, but, in addition, also permitted qualified Architects or Planners or Junior Engineers or Draughtsmen. Provided, however, they are registered with the Corporation or Municipality, as the case may be. The purpose for registration with the Corporation is obviously to ensure that the specified professionals, who sign the documents, plans and specifications submitted alongwith the notice for erection of building, should be available to the Corporation as and when required. This provision, according to the respondents-State, was necessitated considering the low number of Architects in the region, in particular, State of Himachal Pradesh, as compared to the exponential growth in the construction activity during the relevant period. That has been highlighted in the tabulated chart placed on record vide Annexure RA/3 from pages 253 to 255.
