During Singh's tenure as Vice Chancellor of Delhi University, the Delhi University Teachers Association criticised his leadership as being authoritarian. In 2013, the President of the association claimed that dissenting voices were silenced, and called Singh's style "feudal and autocratic", and two years later, Bhaskaracharya College of Applied Sciences principal Manoj Khanna resigned from his position, also referring to Singh's "autocratic" attitude. Khanna claimed that colleges were required to submit false affidavits to the All-India Council for Technical Education (AICTE) in order to get approval to run BTech courses, something that was denied by the university's spokesperson.
Singh was also accused of financial and administrative irregularities. A ‘White Paper’ released by Delhi University Teachers’ Association (DUTA) alleged financial and administrative irregularities in functioning of Delhi University, like diversion of OBC funds for purchase of laptops or flagging off ‘Gyanodaya Express’. The Ministry of Human Resource Development, Government of India, after approval of the President of India (who is also the Visitor of Delhi University) issued a show cause notice to Singh regarding these allegations. Singh responded to the showcause notice denying every charge but HRD ministry turned down his request for withdrawing showcause notice. Noted Academics including ex-President of the Indian National Science Academy, Krishan Lal, former Director General of the Council for Scientific and Industrial Research, SK Brahmachari, Keki N Daruwallla, ex-Vice President of the Indian Academy of Sciences and a host of academics from JNU, Jamia and Banaras Hindu University and Ex-DU Vice-Chancellor "backed" Prof. Dinesh Singh raising concern over the manner in which, "the autonomy of the university was being compromised".
The government decided not to process his reply to the showcause notice as he had barely few months left in his tenure and few senior Cabinet ministers pleaded for no action against him in order for him to finish his full term.
The HRD ministry, on 7 October 2015, requested the Visitor to send Dinesh Singh on 'forced leave' on the charge that Dinesh Singh tried to derail the process of appointment of his successor. However, the HRD ministry had to withdraw the request as the Visitor Pranab Mukherjee was not convinced if the DU VC should be punished with barely 20 days left of his term. The Visitor asked Dinesh Singh not to continue for a single day beyond the last day of his term. However, Dinesh Singh denied the charge of intentionally derailing the process of appointment of his successor and asserted that he will not continue a day beyond his tenure as is being speculated. In spite of just 20-odd days left for the completion of his term, a large number of teachers and students came out to protest in front of the Vice Regal Lodge demanding his ouster.  Not only did the activists of National Democratic Teachers' Front and Academics for Action and Development (Rathi) protest against Dinesh Singh. but the demand for the removal of Dinesh Singh has seen the archrivals Democratic Teachers' Front (DTF) and Academics for Action and Development (AAD) to join anti-VC protests by Delhi University Teachers Association. J Khuntiya, chairman, AAD (Rathi) alleged that the delay has been intentional to ensure that Umesh Rai, a member of the team of Dinesh Singh becomes eligible for selection. One of the names included by Dinesh Singh in the search committee for the selection of new Vice-Chancellor is Vinod Rai. 
DUTA has also recently charged Singh with plagiarism and has sought investigation into these plagiarism charges against him.
Singh was instrumental in initiating Four Year Undergraduate Program (FYUP) which met with a lot of resistance from different quarters, after which the programme was scrapped as per the directives of the University Grant Commission(UGC) . Thereafter, Singh announced his resignation  but later retracted it.
