The tunnel in Dundee under the eastern flank of The Law seems to have been added as an afterthought, and difficult tunnelling conditions proved expensive; moreover land acquisition was considerably more expensive than had been allowed for. The Law Tunnel was completed on 21 January 1829, but later in the year the works generally were reported as at a standstill. Landale was dismissed from the service of the company, amid criticisms that he failed to control the contractors properly, and that the estimates had been considerably overspent. The company had exhausted all its capital, and amid considerable acrimony, it decided to seek authorisation for additional capital and for borrowing powers, and these were granted by Act of 29 May 1830: £10,000 in additional shares and £20,000 in borrowing. The Act also conferred powers to extend the line in Dundee to the waterfront, "through the streets", and "the additional funds enabled completion of the line".
