The strength of the High Court is determined by the President, depending upon the workload. This means that the President has the authority to decide the number of judges that will be appointed to a particular High Court based on the volume of cases and workload that the court has to handle. Let's further explain this answer in detail:

1. Role of the High Court:
The High Court is the highest court within a state's judicial system. It has the power of superintendence over all courts and tribunals within its jurisdiction. The High Court is responsible for ensuring the proper administration of justice and the protection of fundamental rights.

2. Determining the strength of the High Court:
The strength of the High Court refers to the number of judges appointed to serve on the court. The number of judges is crucial to ensure the efficient functioning of the court and the timely disposal of cases.

3. Workload as a determining factor:
The workload of a High Court plays a significant role in determining its strength. The workload of a court can vary based on factors such as the population size of the state, the number of pending cases, and the complexity of legal issues being dealt with.

4. President's authority:
As per the Constitution of India, the President has the authority to determine the strength of the High Court. This authority is exercised based on the recommendations of the Chief Justice of India, who consults with the Chief Justice of the concerned High Court and takes into account the workload of the court.

5. Importance of workload assessment:
Assessing the workload is essential to ensure that the High Court has an adequate number of judges to handle the cases efficiently. If the court is burdened with a large number of pending cases and a high workload, it may require more judges to expedite the disposal of cases and provide timely justice to the litigants.

6. Balancing factors to determine strength:
While workload is a key factor, other considerations may also come into play when determining the strength of the High Court. These may include the availability of infrastructure, the number of pending vacancies, and the need for specialized benches to deal with specific areas of law.

In conclusion, the strength of the High Court is decided by the President, taking into account the workload of the court. This ensures that the High Court has an appropriate number of judges to handle the cases efficiently and provide timely justice.
