Methodology underlying the tables showing counts of unique hereditaments linked to formal challenges/reports (Tables A1.4 to A1.6, A2.4 to A2.6 and A3.4 to A3.6)
To aid interpretation of the tables showing counts of unique hereditaments linked to formal challenges/reports, this section outlines the underlying methodology and through examples shows how individual properties contribute to the statistical tables.
1. Tables A1.4, A2.4 and A3.4 – Counts of unique hereditaments linked to “received” formal challenges/reports/cases
The counts shown in these tables are based on the unique hereditaments linked to “received” cases. We look at the hereditaments linked to a case when it is first received.
For example, if the VOA received the following formal challenges, the statistics shown in the tables for the relevant BA would be:
| Case | Code of Grounds | Hereditaments linked at start of case | Unique Count of hereditaments |
|---|---|---|---|
| 1 | 01 | Heredit A | 1 |
| 2 | 01 | Heredit B | 1 |
| 3 | 08 | Heredit B | Not included in calculation |
| 4 | 09 | Heredit C Heredit D | 2 |
| 5 | 09 | Heredit E Heredit F | 2 |
Table A1.1 = Number of formal challenges received = 5 Table A1.4 = Count of unique hereditaments linked to formal challenges received = 6
2. Tables A1.5, A2.5 and A3.5 – Counts of unique hereditaments linked to “resolved” formal challenges/reports/cases
The counts shown in these tables are based on the unique hereditaments linked to “resolved” formal challenges/reports/cases. We look at the hereditaments linked to a case when first received as well as the hereditaments linked to the case upon resolution. The reason for looking at properties linked to cases both upon receipt and upon resolution is to ensure that all properties that are created or deleted from the rating lists as a result of splits and mergers are picked up whilst ensuring that properties linked to many cases are not double counted.
For example, if the following formal challenges were resolved in quarter, the statistics shown in the tables for the relevant BA would be:
| Case | Code of Grounds | Settlement Code | Hereditaments linked at start of case | Hereditaments linked at end of case | Change | Unique Count of hereditaments |
|---|---|---|---|---|---|---|
| 1 | 01 | Withdrawn | Heredit A | - | 1 | |
| 2 | 01 | Agreed | Heredit B | Heredit B | Amend | 1 |
| 3 | 08 | Agreed | Heredit C | Heredit C Heredit D Heredit E | Delete New – Add New – Add | 3 |
| 4 | 09 | Withdrawn | Heredit F Heredit G | - - | 2 | |
| 5 | 01 | Withdrawn | Heredit F | - | Not included in calculation | |
| 6 | 09 | Agreed | Heredit H Heredit I | Heredit H Heredit I Heredit J | Delete Delete New – Add | 3 |
Table A1.2 = Number of formal challenges resolved = 6 Table A1.5 = Count of unique hereditaments linked to formal challenges received = 10
3. Tables A1.6, A2.6 and A3.6 – Counts of unique hereditaments linked to “unresolved” formal challenges/reports/cases
The counts shown in these tables are based on the unique hereditaments linked to “unresolved” cases. The counts are formed based on the hereditaments linked to a case when the case was first received. The example shown in section 1 above illustrates the method employed.
