What is the effect of non-filing of the articles of incorporation within the required period?

Failure to submit the by-laws within 30 days from incorporation does not automatically dissolve the corporation. It is merely a ground for suspension or revocation of its charter after proper notice and hearing. The corporation is, at the very least, a de facto corporation whose existence may not be collaterally attacked. (Sawadjaan v. CA, G.R. No. 142284, June 8, 2005)
